How much would it cost to upgrade from A5 Extra (Sybex) to A6 Extra (Conitec) or A6 Comm. I would at least need Comm. because otherwise the downgrade wouldn´t work mmmhh... - Pro. is too much at the moment I think. Could I pay with bank transfer (Überweisung) because I don´t have PayPal or a Credit Card and I don´t want to give away my account information in the internet with other words is there a opportunity to buy 3D GameStudio in a normal store - Saturn e.g. only offers Sybex versions.
