Free up space by deleting BF2 levels?

[BoonieHat]

I have re-installed BF2 just to play PR on my new system. I'm using an 80gb intel SSD drive for the OS and programs. 80gb is not a lot, so I figured I could delete the original BF2 movie files, and maybe the level files. However, now I get a message like "the server has denied connection" when I try to log in. I'm assuming PR doesn't really need "Wake island 2008" vBF level file(or any others), so is there a way to play PR without the large 1.5 gigs of vanilla maps?

Maybe this is a cheating screen - making sure the program files aren't modified? If so, could files not used in PR be excluded from the scan? Or are the original map files actually used?

orginal files need to be there period! removing them will cause the game not correctly working!
