Hey Jumper Guys

I need help with my application, cod4 is always sucking around somehow and I don't get how to post a thread in tek9-forums LOL! So I have to bother you guys, I'm so sorry
First of all, is cod4 competititve gaming dying out? Every well known star/clan like WesternWolves/phantasmagoria/phatasy (of course I had to mention him

) is out of buisness somehow
But now to my problem. I made a few of my friends play CoD4

and they wanted to play 1on1 so we tryed to create our own servers and I even tryed it with dedicated servers. However, since I started that fcking dedicated server, my application won't start up anymore. So, it opens it up but when the black screen appears, it suddenly crashes without any error's or whatever, it just closes. I'm just feared of reinstall the game because of my stats and all my work behind my profile. I played like 5 times up to lvl 55 and I actually don't want to redo that shit again. PLS HELP ME IF YOU CAN! THANK YOU GUYS!
P.S. yes I know, I'm so incapable in everything I do right now :PPPPP
