Won't let me on....

[FrozenMind]

Okay, It's me and my problem....again.
I cant connect most of the time and when I manage to get in the game lags very hard and disconnects eventually.

In about 2 months of facing the problem i did many things:
reformatted comp
tried RO from another comp at home
reinstalled RO
called ISP (they say everything is fine)
and I'm sure there's no virus/spyware on my computer
also I guess everything is fine with the server...

Is this the end for me??
