I know this is an older game but I've yet to upgrade so I still enjoy the Multiplayer games. However, I've been having trouble with the UO expansion. It worked for a while and then stopped. It won't even start up. When I try to run it, it looks like it is trying to connect/open but the screen just flashes a few times and it says CoDUOMP has stopped working.
I have read there are problems with running it on Vista but I don't know if there have been any solutions determined. I don't know if that's even the problem because, like I said, it was working fine for a while and then this happened. I uninstalled and reinstalled and it was working for a couple of days and now it's having problems.
I've tried running it as administrator, in compatability mode (Win XP, 2000), and even tried running it off one of the 4 processors (as I heard that multiple processors can cause problems). I have the latest patch downloaded too.
