Black Ops ASCENSION error

Hey guys i got rownans dlc files and installed
now when i wanna play ascension
after 5 seconds on loading screen it crashes
and there is a error
zombie_floodacc_n


im searching to fix the problem but nothing is working

is it rownans files if it is

where can i get proper dlc files that are free for pc?
most fucking downloads are on *********
fucking scam ******

plesae i wanna play ascension badly :S

i also used black ops dlc optimizer

yeah rowans files suck
if you download the unlocker there you see a download link in it
use that one for the good files

they only have to restart it
and i had the same problem =.=

go to unlocker thingy topic

and on last page u see some posts by house and that are the correct files
