So I was trying to buy Dune 3 trough the official shop page, but everytime I click on complete order I'm just shown the following message (screenshot attached). Tried twice and I gave up, so I went to Thomann to buy from them, although the price was steeper.
I purchased trough paypal express, and now I get this message (see screenshot 2).
I'm extremely disappointed to say the least. I've been saving money for a year to buy this plugin. Any help would be appreciated.
