Greetings. First off, I gotta say that I love GameEx! I just got my arcade running alst week and chose GX as my front end and even paid for the full version day one! So now for my issue..... Everything was working well until last nite until, for no reason what so ever, entering any menu which displays a database list (favorites, emu list, MAME games, etc) causes GameEx to crash. There was nothing out of the ordinary that started this. We played a few games, walked away, attract screen kicked in, woke it up, chose another game and BAM! It hasn't worked ever since. I have tried the following things to try to resolve this: 1) delete .cache files - same 2) renamed data.mdb and reinstalled - same 3) renamed old install directory, fresh install of GameEx - it allowed a one time update to the MAME game list, but when trying to enter a menu to see the results it crashed the same way 4) revisited Windows update and got everything, including all .NET fixes and patches - same on both old and fresh install 5) downloaded new installer via GameEx web site and installed that twice... once as fresh install and once over the top of original install and each yielded the same results as above Each time it crashes, the debug log (error list, whatever you guys call it), is the same and is attached. The main error I see is "Index was outside the bounds of the array" and each time it is accompanied by a Windows Event in Applications for .NET 2.0 Runtime, Event ID 5000. It is quite predictable. I read through the forums and followed suggestions which lead me to my steps laid out above. I Googled the .NET Runtime error directly and most results seem to elude to the backend being the cause with no real hotfixes or tricks around it from my end. One suggestions was to enable legacyUnhandledExceptionPolicy in aspnet.config but that didn't seem likely but for kicks and giggles I tried that too to no avail. Any suggestions are appreciated. I really want this running!!! I finally got to build an arcade system last week and its killing me that it died and I have no way back already. I tried other FE's and they work (but stink compared to GameEx IMO) so I want to stick with it. I really would rather not wipe my Windows install if possible, but I fear it is going that direction. PC SPECS: Windows XP SP3 running native on Core2 Duo 2.0 with 2GB RAM The PC is dedicated to the arcade and sees no action otherwise. All Windows Updates applied Thanks for taking the time to read over this. I hope someone can be of assistance. application-event-viewer.txt gameex-error.txt
