Hey, I installed Undead Patch 666 and everytime I run the game it closes and tells me I do not own Gmod 10...I created 2 new steam accounts and followed instructions to a T..could it be that I have a REAL account installed on this computer with a purchased game?
to make it work you have to:
1-put all the downloaded files in the steam folder
2-run the "UnDead - Install & Launch.bat"
3-then run "UnDead.Injector.exe"
4-run steam.exe and it shoud work
