Ok, so this problem has been annoying people for quite a while, but mine is a lil` bit different. So me and my friend were playing cod the other day when I came across a weird problem. There was a "key code in use error" so I searched the net and reentered my "new" key code. I restarted my cod and enered the usual server I play in. And BAM - I am level 1 with nothing ........ I searched the net and found out about the MPDATA file and how it corrupts, and the sh*t about how its bound to key code. I found a solution on how to fix this, but there is a MAJOR problem. My old mpdata was bound to the key code that I deleted and now I cant find it anywhere. The regedit and everything doesnt show a sh*t... Please help me find the solution cause I want my old level and achievements back. BTW I even tried to enter the corrupted MPDATA file, to see my key (no luck) but I heard it might be there.
