I accidentally deleted a full install of Ghost Recon and the mission packs by dragging and dropping it into the trash. Now, after installing Ghost Recon Retail, the install screens for DS and IT both give me the option of either uninstalling DS or IT or playing DS or IT(when they aren't even on the computer!). Even the patches say my version of Ghost Recon is newer than they are when I just installed the game from scratch. I'm absolutely at my wits end about this. And by the way, I've tried deleting the regedit entries as described on Ghost Recon.net. Nothing works. Please help me.
