Glad it's not just me. I've sent an e-mail to customer support so I'm curious to see where we get the fastest reply. I've purchased Resco Explorer end December 2006 so I should be allowed a free upgrade no matter what. But indeed v6.00 to 6.15 should just work with the old key, and the page where you can request your registration keys didn't provide any help either since it provided the old (v6.00) key.
