I've had some stuff on my RMAH and received an email notification for all of them saying something like

Greetings [Name] (ZaM),

Congratulations on your successful auction in Diablo III!

Item name XXXXXX
Time of transaction 27 Feb 2013 04:23 AM PST
Sale price $0.00
Transaction fee $0.00
Applicable taxes $0.00
Your proceeds $0.00

Now I can't access the AH to check if the items are still there.

What happened, and will I get my items back?
