ok.
first , you dont get an fully grey screen anymore. thats a good thing.
try a bigger displacement map… 2048 pix.
how did you do the displacement?
try Multi Displacement 3 under Zplugin.
do a R32 setting and use this code DE-LBEK-EAEAEA-R32
the edges seems not to big of a problem. i watched a Meat Meyers video and he had the same edge problems… seem that Zbrush makes the map a little bit bigger, so the egdes wont show up on your mesh.
Multi displacement exporter 3 crashes every time I try to create all and says there’s an error…
Got it sorted! Reinstalled Displacement map exporter 3 and now it works, huzzah! Thanks to everyone who kept helping me out, was greatly appreciated!
Great, glad to hear you are making strides forward.
Post some pics for us! 
One more thing - I have a proper displacement now, but when I apply it in 3dsmax no detail appears, just a wierd bloated mesh…
Have you tried a 32BIT to see if it is giving you the same problems? Can we see a screenshot of your seetings for the exporter in the alpha pallette?
I managed to get it looking alright, I had to play around with the displacement intensity in max to get it halfways decent. I’m aware max 9 has problems with displacements anway. I think i’m alright now!
