conmanclient2.exe error

I'm writing app on Casio DT-X7 running Win CE 5.0, using VS 2005 and CF 2.0. As activesync 3.8 is not an option, I choose the "ActiveSync-less" approach .

When launching the conmanclient2.exe, it exits with the following error (pasted from the error log file):

daa77ca6:da2ad142: Time: 9:54:59 PM: Exit: WinMain HR=80070057 

Does anyone know what is "startListening loadTransportLoader hr=8007007e", and how to fix it?

I have fixed it with ActiveSync 4.5

Basically the device plays well with the ActiveSync 4.5. Then I setup a partnership, and conmanclient2.exe complaints no more.

I forget to say that the device got the english Win CE 5.0 flashed before the conmanclient2 error. It seems that the partnership has made some setting for conmanclient2 to work.
