I am having a very strange problem with H2V and some of my friends are too. I had it installed on my pc for 6-8 months and it worked well before. Now when execute the program it goes into the xbl gamertag screen and then asks for the gamertag which I need to recover on the PC. This is where the problem starts. It says I have an incorrect tag or password and boots me out immediately. My windoze firewall is off and the only thing differen on my pc now is Norton 2009 and O & O Defrag. Help !!
