Bots gun game takes too long to load then gives me a (null) error

[mohamadalkhatib]

Hey yall, I have a problem with my call of duty: black ops game(cracked), its version is 100.0.0.0.0.0, I got it from a games shop that installed paid games for free, I used to play it in playstation 4, I got it on pc mainly so I can play agaisnt bots with gun game mode in combine map, but where my excitment goes, I finished all the settings and started the game, at first its started loading, then noticed its loading for long time than it should, then it literally took almost 10 t0 15 minutes then got me back to the setup menu following with the error (null) and thats it, I tried again and again but no hope, And when I start the game itself, I see the multiplayer tab is grey, so I looked it up and was told to create a mods folder then make a folder named "usermaps" and I did and then loaded the mod and kaboom the multiplayer option was available.
I would appreciate it if I get any replies and fixes and solutions. Thank you very much!
