--- Comment #2 from Nikolay Sivov bunglehead@gmail.com 2010-10-23 11:29:51 CDT --- What is your reported Windows version? It's also interesting to try it on Windows (XP for example), probably application detects version not from reported version value though.
Also please attach +relay log from startup to message box.
P.S. there's a simple fix for that.
