Hello, I already sent the message through Priority contact form however for any case I'll duplicate it here. I've been purchased LnS some time ago, now I've re-installed the Windows and so reinstalled LnS. When I've entered email/serial number initially it did work. However recently I've upgraded the drivers for my ATI card and every time LnS starts (which is upon Windows load), it asks me to enter registration information again and again. However when I am entering my email and serial number, and click "Validate" button, email field's value disappears, s/n field's value stays filled in, but nothing happens. The program does not become registered. Your advice is highly appreciated.
