Your working copy got somehow corrupted. Don't know how that could have
happened, but a checksum mismatch means a corrupted working copy.
So all you can do now is a fresh checkout. Either of your whole working
copy, or you can delete the subfolder where the file with that error is
in and then update the parent folder to get that file back (make sure
that the .svn folder containing the data of this file is deleted before
the update).

After that, it should work again fine.

Hmmm - as I come thinking of it: this happened to me once some time ago.
I then found out that my HD is slowly showing its age and that several
sectors (including one belonging to the file in the .svn dir) got
damaged and had to be fixed (Windows "fixes" that with the scandisk
program by simply removing that sector and marking it as damaged).
Maybe you should do a check of your harddrive - better be safe than
sorry! You learn to do that regularly once you've lost a whole HD full
with important data (I'm talking from experience here: one evening, my
XP suddenly crashed. After the reboot, my HD made _very_ strange sounds
and wasn't even recognized by the BIOS anymore!).
