@roppy:
There is an support-subfolder in your gamedir.
One for BF2 and one for BF2:SF.
In both folder you can find an EXE-File with "_code.exe" at the end of the filename.
Run them and enter your original cd-keys.
After that you need your cd-key encrypted in your registry. For that reapply the V1.4 full - Patch.
This should help.

Thanks GLH :)

I tried re-entering cd-code so many times but never installed the patch afterwards.
and guess,............ it worked !!

Thanks again for your post
