In RCT, when I try to load my recent saves, and saves I downloaded from the internet, RCT says that the files contain invalid data. I can load old saves. I tried getting the latest patch, but I still have the same problem. I have the Corkscrew Follies expansion pack. I would email Hasbro support, but when I try to visit their support site I get a 403 forbidden error...
