Invalid server certificate when registering purchase

I recently purchased a license for Devonthink, and am having an issue getting it registered. When I enter my name and product key, I get an error indicating that the certificate for the server is invalid (error message screenshot follows). Pressing the only button (OK? - seems like there should be ok and cancel, but…) just dumps me back to the registration screen. If it is a problem on my end, any ideas?
