Blake Stone Aliens of Gold can only play Episode 1

[ᴏᴠᴇʀᴊᴏʜɴɴʏ]

Hi I bought the throwback pack after completing the first episode I wanted to start the other episodes and now I have the problem, that the game crashes back to desktop when I try to start Episodes 2, 3, 4, 5 and 6. I only can play the first episode? Can anybody help me. I was waiting for years to get the full version but right now I am pretty disappointed. :(
