Sniper Elite 3 disappeared of my system for some strange reason so I re purchased a Key number to install but keep getting a message trhat SE 3 is already on my Library. I thought I could Uninstall the first one and then install the new one., but no I cant find the original Sniper 3 anywhere , so cant uninstall it and therefore cant install the latest one. Any Ideas where I can find whats left of the old Sniper please ?
