Nebulars bypass

Hey i am just out of school and saw the bypass. Now it says its for 4.7 but there was an update to 4.8.1. I dont know if the version has anything to do with it. But whit the bypass is says "invalid client please reinstall". This is what i do :
Start launcher located in BIN. Select dekaron.exe ( already tried the unpacked one stil doesnt work) and launch. It loads I login and select server. I have no hacks on or anything. but get invalid client am i doin anything wrong?

Thanks in advance!

works fine for me, try not to target unpacked dekaron, instead target normal dekaron exe and update offsets and hack ;)

In case the new bypass creates a CRC folder you need to delete it after each new update and run the game once with the bypass with unedited packfiles.
