It appears as though OCTGN will freeze and or crash after a period of time. It will then not be able to be reopened without restarting the computer.
It appears to happen on Windows 7, but that's so far the only thing in common.
Thanks for all the info, it should help us solve the issue. Currently it's the holiday season for us so we haven't had much time to look into this issue. It's fairly complicated because this doesn't happen to all users, only a select few, so we need to first figure out a way to duplicate before we can hope to fix it. That's why the more information we can get from those with the issue, the better a chance we have of fixing the problem.
I have been having this problem. I am running OCTGN on a 2014 MacBook Pro using Windows 7 Professional (64-bit) via Boot Camp. I tried using the .NET Framework Repair Tool that was recommended to me earlier, but it did not solve the problem.
I've been running into this issue across multiple games (and even just the OCTGN deckbuilder).
HP Pavilion dm4 laptop. Integrated Intel graphics card.
Intel Core i5 m 460 @ 2.53 GHz
4.00 GB RAM
Windows 7 Ultimate up to date.
I'll be asking for more information as I dig deeper into this.
