When I am asked to purchase one, and brought to the area of the Xbox Live marketplace where I should be able to purchase one, I get an error message similar to "No memberships available at this time, please try again later." for the past week. I have tried manually browsing to the Phantasy Star Universe section of Xbox Live Marketplace and going to the PSU section of Xbox.com, but to no avail. I called Xbox Live and they said to wait for memberships to become available. Anybody else having this problem?
