Hey I love the sims so much. Well I accidently uninstalled my sims. So I tried reinstalling it I can get the first one installed but for the expansion packs it says: This installation package could not be opened. Verify that the package exists and that you can access it, or contact application vendor to verify that this is a valid windows installer package. I tried everything I could. I got these game installed once before. I am really bored playing just the first one I really want to play my expansion packs. Someone PLEASE help me!!!!!!! I am desparate.
