Cannot debug application

[skoro]

Hello!
I install Pelles C 7.00 and create simple application for windows mobile smartphone.
Application builds fine. I connect phone via ActiveSync and run application. Application run fine on phone. But debug warning me on phone about poide.dll I confirm Yes and then Pelles C failed with message "Unable to execute '<remote server>'. Invalid signature.".
How can I solve this problem?
OS: WinXP SP2

With my old HTC Touch Diamond 2 with Windows Mobile 6.5, I had the same problem.
With my very old ASUS 696 with Windows Mobile 6.1, it worked.
It seemed to be a problem with the permissions.
