You Alt Tabbed out and can't get back in?

Nexon has played a trick on users

This is why:

You say deleting files such as CAV,.dmp files,etc. will help nexon not D/C you and will stop reports from being filed, less lag, etc. am I right?

Well you're wrong, turns out nexon is really hiding it in a folder called Roaming

But there are so many files you don't know which belong to Nexon

and it's constantly showing Nexon what hacks you activate, what files you take out, Reports by people, etc.

They said on their Terms of use that they can scope out your product to see your active processes when you're playing any nexon game and store traces to save what they saw, and at the end of the month they double check it and may ban you for what you hacked
