My first thread. STALKER help?

i have the steam version of s.t.a.l.k.e.r.
everytime i try to save my game, there's a console error message that says 'permission denied.'
can a bro please help me out? i've had this game for a while and i feel like i am really missing out on some fun gayman.

bump.
I've already tried re-installing (and re-downloading as well)

try running as administrator

As in running steam as administrator.
