I recently purchased a new computer (mac). The new computer does not have a disc drive, but I discovered if you enter in the code enclosed with purchased discs into origin then you can still install purchased games. This worked for the Sims 3 base game and University Life expansion, but it is not working with Ambitions. When I try to install it then the game will not load, I only get an error message until I uninstall it. Without ambitions installed the game works fine. Has anyone else run into this problem? And what can be done to fix it?
