cool thankq iel just see what is posed here 1st b4 i do thatI had the same problem when I signed up for my free account again. I had an adenhanced account but I upgraded to paid and now I'm on adfree again. I thought I had heard you need to submit a ticket to upgrade, but I'm not sure if that's true anymore.
You can still get the adenhanced plans but you must place the ads and then request the upgrade. An account manager will review your site then upgrade your account.
