Every time that i try to install the game it never completes, once it hits 100% it just keeps going. i cant get it to work. it goes roughly to 115% then it sais the file isnt found. whats going on and how can i get this resolved.

I have multiple games through GOG and they work fine....this one...not even close.
Well it works for me. Maybe we could help you if you gave us more details. Which files did you download (direct download or galaxy)? Which version do they have? Did you try to re-download them already? Which operating system do you use?
