I lost my CDkey.. I bought halflife a couple years ago. well, i went to play and realized, i lost the inner cover thing from the case, the one with the CD key. Is it possible to contact valve or sierra or something and give them the serial numbers off the box, or mail them the UPC and get a cdkey? I relly dont want to buy the game again, that would really upset me. Any help is welcome.
