The following worked for me on Windows 7 - try deleting the following folders :
C:\Users\youusername.here\AppData\Roaming\Ubisoft\Tom Clancy's Ghost Recon Future Soldier
C:\Users\yourusername.here\AppData\Local\Ubisoft Game Launcher
C:\Users\yourusername.here\Documents\Ubisoft\Tom Clancy's Ghost Recon Future Soldier
Not sure where they're located on Win XP.
This might get you back up and running, since deleting those files and launching with 1.2 installed I haven't had a crash so cant confirm exactlywhich you need to remove.
Looks like in some crash states it is corrupting files then bombing to Yeti error when it cant read them on launch.
