I had a "lockup" last night while playing WoW. I rebooted the computer and now the curse client won't start. I get a message saying that I have a corrupted .Net file......so I've re-installed .Net and still no go with curse client.
Well, I followed the above steps with no success, however, I got the problem fixed. I was going to uninstall and reinstall curse....went to window control panel, add/remove programs and when I hit uninstall for Curse....I got a "repair" option that seems to have fixed it. I had to re configure the options but otherwise all is good now.
