Can you explain in more details? How is it a free upgrade? Or do you mean renewable. Upgrade cost $175. Renewal cost $50,. but only gives u access to vB4 for 3 months MAX. Then you have to pay $175 to upgrade to use vB4.
I own the license and there is a Free upgrade to 4.0/higher.... it is possibly sold on monday....if it doesnt sell ill let you know. -C
