I'm eligible for the discounted creative cloud membership due to me owning Design Premium Suite CS4.
Clicking through the Special Offers and signing in the system confirms this.
The payment system then comes up but after a couple of seconds it disappears.
The issue is not browser specific.
Calling UK sales they cannot sell the cloud, they put you through to what sounds to be an Indian call centre. The Indian Call centre give you a web address. So I can't buy this over the phone either.
Can anyone help?
