getting 2002 time to time . For me it usually happening if "wave" of launcher fail's was have place . Sometimes i can log in just fine , sometimes i have to fight launcher (version check fail, html error , and other one i forgot) then if passed all this 2002 can occur on next few login attempts . It's on my PC .
As for ps 3 after 2.3 nearly same problems started (launcher freeze , cannot connect to server , disconnect from PSN (last one can be PSN problem))
