i keep having the same problem with piry not downloading

[potatobun]

i have downloaded bo2 from crotorrents and installed it in a seperate file on c,games, call of duty black ops 2
for a week now i kept on having this problem. I would play some hours of the game on the plutonium servers normally but after a few hours of playtime the game wouldnt start and would say t6lr.dll or something like that couldnt be found. I found that by reinstalling the game and putting piry on the game again would fix this but only for a few hours again. I kept playing like that and reinstalling the game again and again but then when the new update for plutonium released, piry wouldnt install and would get stuck at 50-52percent and then would say error while downloading. after that i tried deleting piry fron the file but it wouldnt fix anything. I even tried reinstalling the game again but even that wouldnt fix anything. If anyone knows how i could fix this, any help would be greatly appreciated.
Thanks.

this is the exact text that pops up when it gets stuck
Error while downloading file t6r/cef/cef_200_percent.pak: failed to copy: stream error: stream ID 11; INTERNAL_ERROR (1/

The .pak files are large archives. The problem is likely your internet dropping out or being in general unstable.
