EasySync problem

I have recently bought the Acer DX900 smart phone (previously sold as E-Ten DX900). I have run into a known problem with Lotus EasySync pro.

After I install EASYSync Pro I am able to syncronize Lotus Notes. But after restarting the device I got the pop-up Window…“The file “XCPCSyncSvr” cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found.”

The problem, and two possible solutions are described at:

Both solutions do not work for me. There seems to be at least one other person in the world with the same problem on the same machine:

My environment

Acer DX900 with Windows Mobile 6.1;

EasySync Pro 4.2.6 on XP.

Does anybody know how to solve this problem?

Thanks for your time!
