So I got the World Adventures expansion pack about 2 weeks ago now. All worked fine and it was all good- there was no issues.
That lasted for about a week. Now, whenever I try to launch the game from my mac I keep getting a message that says "Please insert disk and retry" but my disk is in there! The computer is reading the disk, as the little icon comes up which says "Sims3EP01" so I don't understand why the game won't launch? Most of the time, the game will begin to launch and go through the opening credits and when it gets to the main menu a window appears which says "insert game disk World Adventures to proceed"
I tried to reinstall the game, and it worked one time then once again after I get out of the game and turn my mac off, when I come back to launch it I get the no disk message. I also thought it may have been the disk, so I took it back to the shop I bought it from and exchanged it for a different one but I am still getting the same insert disk message.
I never had any problems with the original Sims 3 disk, it's only now with the expansion pack.
Does anyone know why this is happening? Any help would be really good.
