Same problem here... plugged my GameEx box into the network for the first time in months and made the mistake of accepting the upgrade - working install instantly went to non-working install. I've tried re-installing all the pre-req's from the links provided on the Downloads page - still no good. Log file is useless as the last thing it shows is the shutdown for the automatic update. Is there a way to download older versions of GameEx - not sure what I was running but I don't think I've updated in at least a year. This is the error I am getting: Event Type: Error Event Source: .NET Runtime 2.0 Error Reporting Event Category: None Event ID: 5000 Date: 1/6/2013 Time: 9:49:14 AM User: N/A Computer: MAME Description: EventType clr20r3, P1 gameex.exe, P2 1.0.0.0, P3 50dcec8e, P4 gameex, P5 1.0.0.0, P6 50dcec8e, P7 de, P8 719, P9 system.typeinitialization, P10 NIL.
