The class restrictions are set up in a file called restrictions.sqf which is under the scripts folder in the pbo. If you delete that file and then go into the initplayerlocal.sqf file and delete the line that references restrictions.sqf. What your really doing is getting rid of the file that actually contains the restrictions, and then getting rid of any line in the whole pbo that references that file. If you completely remove the restrictions.sqf file, it will also remove the spawn protection. If you wanted to get rid of restrictions but keep the spawn protect, you could go into the restrictions.sqf file and delete all of the weapon classnames that are restricted. That would leave everything intact, but it wouldn't actually restrict any weapons. I hope this helps!
