Same experience. Then I just tried to exchange some Continental miles for Delta and their stupid/slow web site (I have a 50Mbps FiOS connection so I know its not on my end) cannot seem to recognize my credit card no matter how many times I try to enter it. No chat support during business hours and and apparently no email response either. Something tells me they might be in financial trouble.

A shame really. The business model seems plausible and could work but their execution has been awful.
