Thanks for the help, but it did not seem to work
Okay, here’s everything.
When I downloaded the 1.5 upgrade, I downloaded it to C:\Downloads. Then I unzipped it into my folder C:\unzipped. Everything has been working fine, except for whenever it needed a new serial number. When the clocks changed, of course it needed yet another serial number. I sent in the request and received the new one today. When I went to open it, the messages did say something about ZResources missing on the temporary internet files folder. The ZRescv151.ZRS is in the folder with ZBrush already. I tried reinstalling 1.5, but the same error messages popped up in the new one. I tried deleting the configuration, the .mem, and the .zrs file, hoping the problem was one of them. None of that worked, so I changed the names back to normal. Ugh! The image below is of the files I still have.

This is the first of many messages that comes up.

I re-installed ZBrush twice and tried all the renaming tricks. Is there anything else I can do? If it helps, I am working with Windows ME.
Thank you for your help.
Edit:
Oops, I forgot to mention that after the first re-installation, the missing files were in Common Files. I am getting so confused! sigh
