This error has never occured before. This is the first

So.. What the hell is going on?
I never changed my username or password.

I think your problem lies in the "*** Your forward and reverse DNS do not match.." message.
Resolving your IP Number 82.131.30.82 leads to altromax.ee, while resolving altromax.ee leads to 80.79.115.206.
Obviously these do not match. They should!
You can test this with mIRC's /dns command.
First type /dns 82.131.30.82
Then type /dns altromax.ee

Ok, i did. Now what?'
They don't match..

Well there isnt much you can do about it! If your IP is dynamic, you can wait for it to change and see if itll correctly reverse resolve. You could also try calling your ISP (internet services provider) about it, or (a rather extreme solution) getting a new ISP.
