I have four characters I used, one main and three alts.

My main is in Typhon, and since I have a problem with my computer I can't access PvP areas and I can't complete SMN job quest. Everytime I entered it always either froze or crash.

For days ago my brother helped me clear the quest with his computer, hoping I can finish current level caps but suddenly it crashed. Now everytime he tried to access my main it always quits the game. Today I tried logging back in only to see the game froze and unable to quit or reset the game so I had to shut it down manually.

I don't think it's the computer since it happened with two different PC.
