Unless you blocked yourself in the first place (in which case, do that, but opposite), you don't.
unblock yourself from what? so need to write more
Yes.
you can't.
How do I unblock my browser? I can't access the internet even though my service provider verifies my internet connection. What do I do?
Bungie decided to shut off the Halo 2 servers a few months ago. They had it run for several years and it was losing popularity due to Halo 3, and Halo Reach. They finally shut the servers. But don't worry, you can still play on Vista.
No you can't
You can't unblock yourself. They have to unblock you by going to your page and hitting "unblock friend" It should be right where it usually says "Block Friend" If they just un-friended you then try re-adding them. If they don't unblock/re-add you they obviously just don't want to be your Facebook friend anymore.
yes it is. it would be announced if they were shutting down the servers.
At this precise moment, it is currently unknown. Halo CE Anniversary will, however, use the original halo's campaign levels, but will use the multiplayer system and indeed servers from Halo: Reach.
Install setup files, and update to the newest version.
You cant unblock yourself if they blocked you but if you blocked someone you can unblock them by going to your account then settings, in the settings you will find block users, click on edit then ull know the rest :)
there is no way. i have tried. you have to wait 48 hours and do not log in in that time.
