OK. I followed the instructions you sent so far and... well, it's acting finicky still.
I booted up CnCNet, selected TS, got the main menu and picked Single Player. Computer freezes, keeps playing sound and music and the cursor moves, but it's totally unresponsive for a good few minutes. Then CnCNet crashes and it refuses to open when I click the icon. I opened up force quit to shut it down if it was still running, and it isn't even an option. It's off, but unresponsive.
