Now I'm really impressed with ASUS. They responded the same day and provided me with the solution I needed. (I should have tried their suggestion but I didn't think of it)
Anyway here is the pertinent part of their reply.
Dear Valued Customer,
Thank you for contacting ASUS Customer Service.
Please try to clear out the DMClient cache and data ( Settings -> applications ->Manage applications -> all ->DMClient).
Then please try to hold the power button down for 10-15 seconds to reboot the device. If the problem still remains, please press Settings -> applications ->Manage applications -> all ->DMClient Force Stop.
If you continue to experience issues in the future, please do not hesitate to contact us.
