Yes - the folder is there. I tried MP after installing the game but before patching and MP worked ok.
I have not yet experimented to see which patch is guilty for MP not working...
I've had no probelms with MP previously. Now I patched the game to 1.40. I had to reinstall the game and the do patches 1.20, 1.30 and 1.40. Everything else works fine BUT:
When I click on MULTIPLAY - NEW there are no maps to choose from. Just the empty page...
I'm running on Win 98.
