Beginning player here.
I got KPN as my Dutch ISP. I have encounter the 2002 error the day before the 2.2 update and after. But the 2002 errors after 2.2 are more frequent.
Ah well. Just gonna wait this one out and see if it is fixed the day after. I have no idea what happen to my archer. Got a disconnection during a battle and now I suffer from the 2002 error. XD
