"Failed to get authenticated by Game Guard" - How to fix this error?

Hey guys,
i currently use the old round skipper (not the new thread, i mean the other one) and it worked fine for me for the last week.
After i started the ijji reactor in win xp service pack 3 compatibility mode to log me in facebook accounts the game crashed after every 2nd round of round skipping so i changed it back to no compatibility mode. Now it's working again but after ~5 rounds i get the error on the picture and the game losses all information about my account except the currently wearing armour and weapons. It also happens ingame with just giving me a connection lost and all my guns changed to standart guns (mp5a3,g3a3,m24 and GLOCK(I don't even have the glock)).
Is there any way to fix that error or make cheat engine undetected in ava?

I never experienced such an error.

Moved.


And did you modify any of the gameguard files?
You can always try reupdating them.

Delete all the gameguard files and when you start up AVA it will re-download them for you.

I never changed anything in the gameguard files except deleting the .erl files like everybody do :D
