I have been told that there are other cases in court / being settled but not yet any specific news on my case.
There is no case. Game-Protect is just an online troll with no skills or experience. There's a reason you have absolutely no contact details of any real person or lawyer.
Earlier you said you paid 5% of your claim in advance. Could you please post the transaction id, and the full email (preferably with headers) of where game-protect confirms you sent him the money.
