So ask your friend to try and join the server you are playing at the moment and tell you the results.
But iam pretty sure if you update the cracked adrenaline from the updater you will get the latest adrenaline.exe that creates another .exe file when you open the adrenaline.exe which is for the paid adrenaline version.
So just stick to the cracked adrenaline version without updating since your server doesnt have a proper antibot system.
P.S A photo after trying to update the cracked version 1.73 and i got the same results after updating the 1.71.
