Data disappears

This has happened to me twice in the last week. I'm using APDL on a Verizon Treo 650. My schedule for november suddenly does not show up in apdl...just a blank month. I'm able to get it back by restoring AirlineLog-200511.PDB from my backup card program. This happened a few days ago while on a trip. It just happened again today. It seems that the file AirlineLog-200511.PDB with all my data (past and future) is being lost or over-written with a blank AirlineLog-200511.PDB.

I've never experienced this before. Any suggestions?
Double Check that "Use Datebook" is set to "No". Refer to F.A.Q regarding the datebook function and the Treo650.

If that does not correct the problem, please email me a list of all installed software on our Treo650 to support@nc-software.com.

Fly Safe!

Thanks for the tip. I didn't see anything specific discussing the datebook function and the Treo 650. Am I missing it?

Could you post a link?
