For me bf2142 and fs could not start, the game started but then failed almost instantly with no errors and I tried as hard as I could to fix it but eventually gave up. I then had similar problems with mount and blade warband and tried to fix that and ended up fixing its problems and bf2142s.

(I am using windows 7 32bit btw)

I went into regedit.exe (put this into search in the start and run it)

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Personal

Then I changed the destination back to the original C:\Users\*insert user here*\Documents         (I think you have to use export to save this, though I'm not to sure)

However I think that it may have automatically renamed documents to my documents in that folder or I might have done it ... I can't remember but anyway it  worked I was able to play bf2142 and save in M%B warband.

I hope this might be useful to someone out there who had the same problem I had.

PS use this to your own disgretion if you're PC dies it's not my fault, perhaps backup your registry first to be extra safe.
