OK- if you have the BETA, you really have a different version of GRAW than the final 1.3 Patch.
I'm sure that you were wise enough to make a copy of GRAW, named 'Copy of Ghost Recon etc' in yr Ubisoft Folder and ran the beta on the original, then deleted it once 1.3 appeared, removed 'Copy of' from the folder it made and patched that version to 1.3.
Oh..you didn't...did you.
Erm...reinstall. Patch, beat head against wall.
