Problem with the lobby connectivity?

[Cronix]

I have been playing PSO2 with no problems, but after the 27th March update.
I always got 630 error when I logged on and entered the lobby.
I've checked my connection, cleaning registry, doing a repatch, re-download the gameguard but still, after I logged on, the game successfully rendered some people around me and then I got 630'ed. It freezed and I've to kill PSO2 process.

Sometimes I dont get 630 if I keep log in spamming, I do quests and when I returned into the lobby, it appeared again. But my data network in the quest zone is stable, never got disconnected.

I wonder if somebody has an idea for this problem

Note: I'm operating on Windows 7 64-bit

Is is anybody or anything on your network downloading anything or steaming since that might be lag causing it, try to do a ping test if its bad.

[Cronix]

no, i have tried the ping test and it's good.
And I tried to direct connect my modem to my PC instead of router, but still the 630 keep appearing

[Cronix]

yes, my graphic driver already the latest
lowering graphic doesn't help either

I got it worked from copying my cousin's pso2..
But after today's patch, it happened again. Anyone know how to fix this?

I had the same problem before, it must be your antivirus or sonar scanner... I use norton antivirus and when I added the pso2 folder located in "program files" and the one in "my documents" to the antivirus and sonar exceptions it worked great again
