Well I managed to install the new studio, so that worked.
Clicking on the "account" section yielded bunch of blue rectangles waving about but not much else.
Trying later gave a log in screen. Tried my forum login thinking it would be linked. Waited ages and then got a timeout message.
Tried creating a new account, filled in the form, clicked continue, nothing at all happend. Tried again, same result.
Decided to have a look around the software instead. It's all greyed out other than the view. Possibly because my printer isn't connected yet.
Noted the infuriating command wheel we were told was finally being dumped last year was still there...
So I had a look at google instead. The software for this looks quite good, and if you don't like it you can use something else instead...
