My daughter lost a Sims 3 Seasons expansion pack disk so I uninstalled this disk properly in Control Panel/Uninstall a Program (Windows7). A few days later I was getting some unrelated glitches & pop-ups that I couldn't get rid of and decided easiest way to do system restore. This put the game back into my system but not by installing it properly. I uninstalled all the games associated and tried to re-install the entire game but now nothing works and I get a popup saying No Disk. I have removed the entire file manually and still the entire game won't work at all. The Sims 3 Seasons still shows in Control Panel/Uninstall a Program, however the icon is associated has been altered from an actual install to what looks like a basic file icon. Is there any help??
