Call of duty mw2 freezing at splash screen? Fear not! A soloution is at hand!

After trawling the internets, I found this soloution on steam’s forums:

The Corrupted file in question is mp_playlists.ff which is located in Steam\steamapps\common\call of duty modern warfare 2\zone\english folder. Go there, delete the file or move it elsewhere (size is 27kb) and the game will download the file and huzzah! No more lame freezes
