Hi people! I´ve just discovered my old Half-life 1 cd. I really liked that game. Today I tried to install it in XP, but it just says that the game has a known compatibility issue with XP. Then it allows me to start the game, I can get into the menu, but when I try to start the game, it asks me for the cd, while it´s inserted in the drive. I have no idea how to make it run Any ideas? Thanks!
