hi, your page looks good, I just submitted a card.
the error you are getting is a generic, service failed to start. If you try to start the 'windows cardspace' service directly from the service control manager you may get a more descriptive message. There were some changes between the RC1 and RTM versions of .net 3.0, so I'm guessing some of the binaries were upgraded and there is an incompatibility. We¡¯re only officially supporting xp w/.net 30 -> vista w/ .net 3.0 upgrades, which unfortunatly doesn't help you much. If trying to start the service doesn't give a helpfull message I'd try uninstalling .net 3.0, then reinstall as a windows component. Also, as a warning, the cardspace store file format has changed, so when it does upgrade your existing cards will be deleted.
