Just brought RCT3 for the mac, done/reprogrammed by Aspyr.
It runs really well right up until i try to place paths, new rides, or delete walls and scenery.
Then the second time i attempt to play the game it says "invalid copy of the game".
I ended up having to reinstall the game, then the same problems repeated.
However i have managed to fire up the game once or twice without the "invalid copy" message.
Anyone had similar issues or have any suggestions?
Note: I downloaded the update off the Aspyr website and it has made no difference wse.
