[size=12]To be able to play GMS again, you'll need to either disable or uninstall your loopback adapter. Disabling it will allow you to re-enable it whenever you want to play SoulMS, however uninstalling it will not allow you to re-enable it. Also, make sure that gameguard is deleted from your hosts file.
First, go to computers , and in the address bar type in ; C:\WINDOWS\system32\drivers\etc
Second, Find the "hosts" file and open as note pad
Third, At the very bottom there should be a line that has "guard.nexon.net" in it delete that whole line, and ONLY that line.
Save, and your done. you may now patch GMS and the hackshield problem should be over
