Trying to complete a purchase on the Ubuntu One Music Store...
...so that I may take advantage of the 6 months free music streaming and 20 GB of storage. No matter which way I input my credit card information, and I have tried every possible way, I get an error stating that the card information is invalid. I even when to 7digital.com's site, signed up for an account, and tried to add the card there, with the same result. The balance is currently zero, as I paid it off last week, so that it not the issue.
