Windows Mobile Device Center crashes when C550 connects

[Guest simonslim]

Dear all,

I experience the following problem when trying to sync my Orange C550 in Windows Vista Ultimate (Dutch x64 OEM-version):

After installing Vista, Outlook 2003, importing the old PST-files and installing the new Windows Mobile Device Center from Windows Update I synchronized my C550. It was detected and a partnership was created; all went well.

The following day I installed a few applications on my computer which interact with the 'ActiveSynch/WMDC application, such as SplashID and SmartphoneNotes. Every time I connect my C550 the WMDC-program crashed and no sync is executed. I tried removing the partnership, but nothing seems to help.

Any ideas?
