First off, don't be a d!ck to someone trying to help you.
Secondly, try to set a static IP address on your PS3 and set that IP address into your DMZ.
Make sure you only enable 1 "Force Host", if two options are present.
If after a few minutes the lobby doesn't form, obviously, back out and try again.
I usually leave it till it start searching for users with ping <120 then I back out.
Try using Team Death match, its the most played game and probably the most players available.
