Copy/paste from FAQ (see first post):
If u are getting
Invalid Client or any other error:
Run the minilauncher.exe and let it normally update Dekaron to the latest version. Now close minilauncher.exe and downgrade the game using SECportal's build-in DownGrader (just press the 'Down' button).
If u will still be getting Invalid client error, then u will need to re-install Dekaron. Then let it fully update. And then use SECportal's downgrader.
And about banning. The GM's are there to ban people. While SECportal was not functioning the GM's had absolutelly nothing to do. And now they are ban-hungry, lol. Anyway, use hacks at your own risk and keep in mind that your char can always get banned while using hacks so don't get too attached to your virtual-self
And as of today, I haven't got any report from our fellow hackers that would indicate some kind of auto-ban feature.
I have a test account which I am using to make and test all of the SECportal hacks. I am using that account from day 1 of the Closed Beta and I haven't get any ban so far. Of course I don't really play Dekaron, but when in-game, I always have some hacks on. And still I didn't get banned, not even once! Therefore I am pretty sure that there is no such thing as auto-ban in Dekaron EU.
To all those people who are disappointed that they got a ban after a few hours/days: I am using SECportal for maney months now without a ban, so if u got banned, it's your own fault.
I also want to state, that nobody is forced to use any hacks, but if u choose to hack the game then
u are the only person responsible for your actions.
