Electric V

I find the Sforzando instruments of Production Voices very usefull. Clear sounds and reasonable price. Recently I started to use the Electric V LE and now I want to upgrade to the full version. According to the website:
"Any Electric V LE payment of $10 or more can be credited towards partial payment of the full Electric V library ..... to redeem your credit, simply email support with your request."

I tried to contact Production Voices via the website, but do not get any response. The same happened with the Estate Grand. It's a pity the such a good product has such bad support.
