I bought Skyrim on CD a few months ago and had no trouble playing it, Steam recognized that I had purchased it
However, my computer crashed and I had to reinstall everything.
In the time between the computer crashing and me reinstalling, a friend shared their library with me and Skyrim also happened to be in that library. Now whenever I try to reinstall from the CD, Steam only has it in the shared library, meaning I can only play it when my friend is not using it. It's not unplayable, just very irritating that Steam is asking me to either purchase again or wait until the library is free.
Does anyone know how to fix this, or if I can install Skyrim not using Steam?
