well this means I will probably have to reinstall the entire stupid game from scratch..
If you have the game and mod then you already have the files. Cal needs them to fix the trainer. they should be in C:\Program Files (x86)\Steam\steamapps\common\stalker or something similar.
I am also seeing the download for 1.4005 showing up as 1.4002 and none of the option works even though it stated game is found.
tried to download 2 times
