If you ordered A7 in the last time, you should already have an A8 key. It has the extension *.dta.

Otherwise, if you got A7 by March 2010 or later, you'll receive an A8 upgrade for free - please just send an email to sales (at) opgroup.de.

You can also order an A8 upgrade key by email at the same address. At least for the next 2 weeks there will be a special early adopter price. It's $299 for a Pro upgrade or $79 for a Commercial upgrade. If you got A7 by December 2009 or later, you'll get an additional $100 discount for Pro and $20 discount for Commercial. I'll also place this info on the announcement page.
