great I will try it tonight.. Ithink
just delete every file in the old protection folder but leave the scriptDatabase.db file dont delete that one, then copy the new protection 3.0 files to that same folder this is no group file or database to worry about, all group info is saved under the rights table inside the scriptDatabase.db file, the new protection 3.0 just adds more options so other groups can also be saved to the rights table, the protection 3.0 is 100% backwards compatible. after you copy 3.0 into the old protection folder restart your server for it to load, note its always best to back everything up before you make any changes at lest then if something goes wrong you can always revert back.
