every few seconds there is a zombie growl, the screen fades to black, then the view comes back, and then a repeat.
twice i have run verify files, and twice 2 files have failed and have been reacquired. And the problem repeats.
The game is patched to 1.4 I didn't have this problem before DLing OWB and running the game
All help is appreciated

i am re DLing OWB, and the Downloader says OWB is 728.8 MB in size, but i read in another thread that it was suppose to be 881 MB. Which is correct?
i finished the DL and did another verify integrity ck, and 1 file failed with a 632 kb DL after i rebooted steam. But i am still having the same problem. any ideas on how to fix it.

i just did another verify, and the same file failed, 632kb and i don't see it with the other old world blues files.
the files are:
OldWordBlues - Main.bsa 664,852 KB
OldWorldBlues - Sounds.bsa 65,633 KB
OldWorldBlues.esm 15,824 KB
OldWorldBLues.NAM 1 KB
are these all the files and the right size? I have DLed them 2x and they are the same size, but a verify fails and a 632kb is redone, but i find no file that size.
I have done the verify integrity several times and 3 times 1 file has failed and it was 632 KB in size.
