I'm not experiencing any problems other than some weird error trapper thingy after 20 mins of working on my park. (I didn't even get to save[:(]). What exactly is going on?
Mine was simply one of those error trapper things that you get like when you use your trainer and you set a rollercoaster's cars to hotdog stalls or bathrooms.
Ok...I've always tried this (and 90% of the time it worked). Try to reinstall the game. Back up your parks and reinstall RCT2. Let us know if it works [:)]
Chances are that it's probably gonna work ok. Mine stopped doing it's error trapper, which probably was just some rare glitch. I was tycooning last night for a while and let it sit for 20 mins and everything ran ok.
