Even with the PLUG-IN system, this baby just wouldn't uninstall.. I wound up manually adding and changing and running the uninstall (from Plugin) over and over again... Finally got it removed from my system.

The reason for the CREATE TABLE statements in the code below is that the uninstaller would drop those tables before erroring out on the "drop arcadepermissions" statements... So that when I put the data in (using the ALTER TABLE statement).. the uninstaller would then croak on a "Table not found" error.. So, as I then had to go back and put the table back in, round and round and round she went... Finally got the right sequence and the uninstaller removed (safely I hope) what it wanted and finished completely..
All I can say is WHAT A MESS! - Here's the SQL statements I had to put in pieces at a time as I ran the uninstaller...

Why is it authors only worry about PUTTING the stuff into your database and really spend little time helping you remove it safely and properly?...
