same problem... kinda...Update!!!
I just finished downloading VU 11.0.0 now I can't log on. All of my systems have green checks. (Win7 64 bit, 3Gb RAM, ATI readon 3200) I ran the tools/ repair cand find a CRC mismatch on file bin32\stlport.5.1.dll. I have allowed repair to "fix" the issue a few times. Reapir keeps finding the same error even after re-downloading it.
When I try to log on, I get through the client loader, and when I select my planet, then it goes full screen and My mouse pointer changes to (I assume) your version of itm and that is where I stop.
I've now followed the other suggestions without success.
Did anyone else have the same corrupt file?
Support got back to me today...
They told me to run as administrator, but it didn't work till I went to right click/ properties/ compatibility tab/ change setting for all users/ run as admin. I did it for both the entropia.exe and clientloader.exe I am now working nicely. I haven't tried only changing one file or the other, so I'm not sure if I needed to change them both, but I can't see the harm in it.
Also that file that the repair utility keeps finding as corrupt is a known issue. Support says it isn't causing these issues, and doesn't affect the game at all. If I could post an attachment, I'd put up a screen grab of the email from support.
Cheers!
