I dunno if anyone has done this I did,
Don't try to remove by yourself the adds, it messes up the administrator panel... the other stuff worked perfectly...
but I had to redo a lot of customized work, because even with installing a backup wasn't working
A lesson learned (in bad way) when someone says Don't is because it meant that way...
Any ways my 2 cents for daring, and an advice others to buy your add free license and contribute with this boonex guys.
