Steinberg Online Shop - can't proceed with my purchase

Thought I might share this here as well…

I’ve been trying for two days now to buy the Cubase 9 upgrade at online shop.

This is what happens:
After I’ve chosen the Cubase 9 upgrade from Cubase 8.5 I then log in (cause I already have an account) and come to the shopping cart where I see my address. It also says I’m a buisness customer which I used to be so I uncheck the “buisness customer” checkbox but the prices then does NOT update to the regular price. Then when I click the big red button to go to the next page it doesnt work. The same address page just reloads.

Pretty frustrating after trying for two days now…

Is it something with my account or is it something wrong with the actual shopping cart?
