In the morning HM2 was working fine. I installed Win 7 recommended non-critical update and reboot. Computer crashed showing blue screen. I shut down and restarted - showed safe mode, started normally and restarted again. After that HM2 crashes immediately on start showing error message box (see attachment). Over 3 hours now I'm trying to fix it with no success. Uninstalled and reinstalled HM2, reinstalled .NET, tried safe mode, removed Win 7 latest update, restarted many times, read this forum etc, etc -- no success. There is no log.txt file. Also no errors appear in error_log.txt file - it crashes too fast (about 8 seconds after the start). When I click on "See report details" on the error message box (bottom left corner) -- nothing happens. I have an old (which I don't use for over 6 months) HM2 on the same hard disk (different folder)-- this one starts fine. Please advise!!!
