Strict nat and other problems need help asap

[monoman01]

I sent an email to steam support though they will take about 5 years to get back so I thought Id ask here, please read and help ...

I didnt add into the email I use mw2 liberation V 1.04 to but i was loading mw2 of it, it went fullscreen rather than in window and everything was back to original settings all exept my rank so all my controls and the resolution etc (this was few days back). This wasnt a big issue as I just re-did everything and it was ok but my nat type too had suddenly gone strict.

I thought I would leave it for a couple of days to see if it got better but it didnt, it kept as strict and occasionally when I loaded using mw2 liberation it reverted back to original settings. (this has now stopped happening after i reinstalled (see bellow) btw).

Its nothing to do with a ban cos i hav been banned 3 months ago :P and its been ok. Im not sure if my nat type and this problem with mw2 liberation are interconnected or if its just coincidence.

As well as this on the third day I tried to uninstall and reinstall mw2 on steam where i met further confuzlement where the redownloaded mw2 was only about 10MB WTF seriously......I need help BADLY!!!!!!!!!!!!!!!!!!!!!!!

HELP ME PLEASE ANY INFORMATION ABOUT WHAT I CAN DO IS APPRECIATED

P.s before you ask no system settings have been changed such as anti-virus or firewall or anything!
