Hello. I haven't played in quite a while and my computer seems to have forgotten how to find and run the proper files when I click on "Play Online", "Skirmish", or "LAN". Whenever I click any of these three buttons a window appears and it says "The system cannot find the file specified".
I assume that the easiest and quickest way to solve this issue would be to uninstall and then reinstall the game. Unfortunately, I have no idea how to safely and completely uninstall the program. I wouldn't want any files to linger. They could cause unexpected issues with the reinstalled game.
Perhaps there is a simple way to fix this without uninstalling. I simply don't know.
I would very much like to play online multiplayer again. Please help.
