Does it launch ok without copying?

Try to re-download and try again.

I have tested the new version with few users. That shouldn't happen.

Also what kind of error it gives?

Edit: I can confirm that there was a bug. Making a quick fix right now. I will replace the rar in a few moments. Just keep with me for a little... The bug should not affect all users, just the ones who were using projectw.org and expresshare forums.
