I just applied port forward settings on my DD-WRT router. Ports 6699 and 6257 are opened in the firewall. WinMX started up fine with a primary connection for the first time. However after running the program for about four hours, it froze and the PC had a warning window saying the program encountered a problem and needed to be closed.
I never had any issues running WinMX in Windows 7 before. It's running in Windows 7 mode, and before this crash, I only ran it in a secondary connection mode. I installed my router without the port forward setting last week and WinMX ran 24/7 without any issues.
Does anyone have any idea what may have caused the crash?
