Charlie-
If you click on "Search"at the top of this page and then type "aladdin" into the Search box, you will discover several discussions of your issue that have run since 2008. Be sure when you search that you choose "30 days and older " in the Thread Age Preference box. You don't need to put anything in the "Filter by Username" box, but probably should choose "Technical support" under "Board Search".
Here is a quote from Paul Schwalen posted last July that may give you a quick fix:
"I have been using the Alladin for 2+ years now and have experienced the same thing. I finally figured out that if I turn the Alladin on before the 8 seconds shutdown has completed (when you shut the engine down) that sometimes this xxxx business happens. To solve the issue I turn the Alladin off at the push button on the display then turn it back on and it usually is OK. (sometimes it takes 2 or 3 tries) Also, I try not to turn the Alladin on before the 8 second shutdown and wait for the shutdown and then turn it back on if needed."
