Can't play online. Need help bad.

Hello, hopefully someone here can help me with my problem. Im having trouble playing Call of Duty 4 and Crysis online. Everytime I try to get into an online game it hangs (on the "Loading" on Crysis and on CoD4 is on the "Synchronizing Game Settings")

I can play other games online just fine,Steam, WoW, Team Fortress 2, World In Conflict. I can connect to my IM's and Firefox with no issues as well.

The only thing that the two share, are they are the only two games I have that run Punkbuster as their Anti-Cheat. I've read every FAQ, posted on the official game forums and I'm playing email tag with an Activision tech support guy at the moment.

I've tried almost everything and at this point I'll try just about anything. I've given admin rights to the programs, I've opened the ports, all my drivers are up to date (video/sound/mobo/network card.. you name it). Ive given exceptions in my Firewall. Im running out of options and running out of hair to pull out =(

Anyone else have this issue? Anything else I can try? Your help is greatly appreciated.

Mike

Sounds like a monitor and resolution issue to me.
Try to set the hertz to 60 in the resolution youre playing.
Sp and MP have diffenet settings so you must adjust even the settings in MP option.
