[Solved]MAJOR Black Ops money problem! HELP PLEASE!

Hey guys, I really have a big-ass problem on Black Ops and I really need major help! So this is my story: My friend was in this level hack lobby that was called AaAaAaAaAaAaAa and I decided to join him because i wanted to 50th level and get 100.000 money, so when i joined the server the console said: Kill your self with a grenade, it's worth it, trust me!" and i decided to do it cause knew it was gonna hack my level and get me money, do i did it, was 50th level and got loads of money, I decided so buy everything and loose all the money I had, did it, then i wanted more and more money, got on the server again and committed suicide a few more times.... so, it was all good, bought the stuff I wanted but still didn't have enough money to buy everything that I wanted. So I was tired and decided to go to sleep and I'll do it tomorrow. So, i got up tomorrow and saw that the server was no longer there, asked my friend and he told me it got banned, and I was like "Alright, I'll earn the money myself" but then I realized I had 0 money but yesterday I had a few hundred left! Thought it was not a huge deal and just went to play on a normal server.... I earned couple of thousands on the server and when the game ended it said i did... so i thought alright... later I open Black Ops and see i have 0 money! I though it was some kind of a glitch... got on a server, played..... Then I realized that every time I earn money it's there and when I got to create a class i can buy what I want, BUT, then when I back out and come back again, I see i don't have the stuff I bought and i had 0 money again!!! And it's going on like that since!!!! I tried reinstalling the game but it doesn't work, its obviously an account problem and I really don't know how to fix it! Oh and yeah, forgot to say this, when the game ends on a server and I didn't get any points it says i need like -403.200 more XP to prestige! And when I get some points it says 0. So, I don't know if i should prestige, but if it doesn't fix the problem ill have only the Pre-Made classes and I wont be able to buy anything! So yeah, this is my problem and I would really appreciate if someone would help me out! Thank you for reading this, bye.
