Activation of premium features -- 2

Hello, I use php shopping cart system. I have bought license for activation of premium features about 2-3 years ago. But the company which was offering this software stopped existing about a year ago and let the domain [login to view URL] expire - that's where I could generate license key for my domain and where the system check if the license key is correct. Now I need to activate premium features but I can't contact them (they went bankrupt and the owner started working for some german company as programmer). I need somebody to edit the code and activate premium features today. I can send you ftp and db information and other details. Thank you. Hektor
