The new plugins links are wrong in some cases. Even though I click to download the mac version I can see by the link that it is the windows version that I am about to download.

In terms of 64bit support check this(already posted here): http://www.polycount.com/forum/showpost.php?p=1194480&postcount=63
Still no joy with activation. Keep getting the “email address provided does not match with the serial key blah, blah” error message. I give up.
Submitted a support ticket. Maybe they’ll “Unleash” it for me sometime later.
Grrrrr…
The same here, I already contacted support, no email yet. :rolleyes:
No email upon waking up this morning…bummer. 
I hope the batches continue to go out throughout the day.
Same here, tried to register online, did not work, now waiting for my email.
Please post activation and/or Registration problems in the Activation and Registration Troubleshooting forum.
Thanks.

seems to me the support system is broken ?!? i cant get into it to download the update
support.pixologic.com is emitting PHP errors, so that’s probably adding to the crush of problems this morning.
-K
Thanks Pixo, just kicked my download off (Uk) and it was only fair that I order a backup CD. I mean let’s face it - FREE Upgrade, brilliant. I feel like I should be paying more. The process was a breeze. I for one think you’re cool. That’s why I’m proud to be a ZBrusher.
The email address provided does not match with the serial key provided at the time of purchase.
I can’t sit and read how beautiful this app is when I can’t register or contact or anything. Someone here has to provide me an information because I can’t even contact support now.
I like how the deformations are now interactive. Awesome
Ah… I forgot to say well done to Pixologic for also providing the full suite of Zplugins for both Mac and PC on time. It doesn’t get much better than that. A massive improvement over previous releases.
Great work and many thanks to all!
I’m wondering if there will be a time we can download the updates via our support account and don’t have to wait for that magical e-mail. That would be the greatest improvement for me at all…and the end of this waiting-hype too…
Luxology did a great job on that. Their support system is the place where you get all your purcased stuff bundled to your account. No waiting, just there…
My feature request for ZB5 
bah no email. 
oh well! I shall wait calmly watching the videos on constant repeat til tomorrow.

Agree, I can’t say that I’m enjoying waiting or that I find waiting for a random amount of time any better than for a known amount of time.
Unknown unknown as someone would have said.
Looks great though, I’m literally drooling, which makes the wait worse.
even after you get the email you then fill out a form where they send you another email that reads like this
Qty. Product Name Delivery

ZBrush 4 Mac OS X (single license)

There has been a problem while processing your delivery. We are already working on this technical issue and may be waiting for information from the software publisher, which may cause short delay. At the latest, this should be solved within 1-2 workdays, although it is generally much less. We will contact you immediately via e-mail upon resolving the issue and apologize for any inconvenience.
So there is no way to download it. The email contains no working links, just your reference number and the error.
You can tell their servers are on overload with the update.
The servers are experiencing ridiculously high traffic right now.
Simply try again every so often. I recommend waiting about a half hour between attempts. That should give things time to settle a little. Everyone repeatedly refreshing at once doesn’t allow the servers to catch up.
Got the same issue but i got my code after clicking request new code 3-4 times. 
The app is awsome!!
Thanks for all the new stuff pixologic.
Goz is the only thing that is not working for me again. But i think i know whats wrong so i wil fix it instantly. Thank god for the programming lessons in school
