corrupt file/memory [8001]

[The-Major]

so i was playing cod the other day for the first time in like 3 weeks.
i managed 30 seconds before being kicked for corruptfile/memory so i thought ill try connect again maybe its just my pc playing up.

so i recconect and play for 30 seconds and again kicked for corrupted file/memory.

i dont wanna have to reinstall again but if u guys can find a way to help me fix it without a new install id be grateful but if its the only way to fix it then it must be done.

i also had to manualy install pb update as it wernt updating itself. worked fine for a week or two but since then its been corrupt file/memory.

This should give you some help. Might be easier to just reinstall. I personally backup big patch files. I have all of CoD 4 and CoD WaW patches saved.

In short, your iw3mp.exe has been edited (Somehow) and PB is kicking you for it. The link below will help. This probably should have been put in Tech Help too.
