So here's my problem:
I've followed the instructions here
and Hammer configurations are set up perfectly but when i got to select PVKII to current game in the SDK menu it reverts back to Half-life 2.
I've also tried to change to PVK config when I'm using the Hammer but when I try to apply the PVK config it says that "Your changes to the active configuration will not take effect until the next time you run Hammer." When I start Hammer again, the configurations have been reseted to HL 2 config again and I don't know what to do to apply those PVKII configurations.
Please help me!
