Well, I saw the support message about the issues and I also read their update saying servers were bang on and everything was fine again.
The shop did not accept any of my (working sound) 3 credit cards regardless of me trying a zillion times.
in the end I managed to do it through PayPal (which used the very same card btw).
As of now, my eLincenser cannot access the server and Steinberg Download Manager can´t go through either. We´ve had that before, and the last time was horrid.
This contradicts the Support last update.
No usual Steinberg email confirmation yet.
So… if any of you is going through something similar, do try PayPal instead.
