I have installed portal with all the gcfs but when i start it up it show the guy's head with the valve in it and then comes the main menu and it says loading but it never does. after like 30 seconds it closes and then it tells me
Engine error
I installed and still no luck but i got a couple questions.
1.Can i run it with the normal steam or should i use the UCL with the SteamEmu
2.I dont have the half-life 2 low violence.gcf does that make a difference but steam says it 100% complete
