are you use a loader? if so, use a loader who doesnt try to delete or modify the hack shield. This cause dc every 10minutes at hackshield serverside check.
If you dont use its may because your firewall or antivirus blocks hackshield or its not correctly updated like you said.
PS: Ksro is the last official server for legits and players who enjoy the be grinding and killing uniques without idiots
