Lashkar Valley Corrupt: getting replacement file

[IAJTHOMAS]

Hi guys,

It looks like Laskhar corrupted when I installed the new patch. I can't launch that map and after a while I get PB kicked for a file mismatch with the lashkar client file.

Is there an easy way to get this one file to replace it? This is the only thing that appears to be wrong with the install, all the other maps work fine. Would be nice not to have to redownload and install.
