1.I just started playing yesterday, but already worked my way to level 35, many challenges and attachments earned, but after changing the resolution of the game, I went back to see that my create-a-classes were a mess. the names were single characters, I had primaries as my secondaries, empty lethal slot, my tactical being "ACR x0", also i saw that i unlocked a bunch of random weapon masteries, many of my earn attachments were gone, the list goes on with whats wrong. I was wondering if any could either help me
A. Get my previous stats back
B. Reset my stats.
2.I can't seem to install the maps for this
I would really like to be able to jump back into the game ASAP since this launch has made me fall in love with MW2 all over again.
