I updated my x50v to wm5 last week (yes, i know it probably wasn't a good idea!!) and tonight tried to sync having done so when I installed the software and once since. Each time I tried I got a "syncronisation error" message, but no explanation. In the end I deleted the relationship with the x50 and re-created it. This works and allows me to sync contacts, email, calendar and tasks, but if I try to add anything else I get the error again - actually, I only get this after closing active sync and starting it again. Otherwise the pc just kind of hangs at the "loking for changes" stage.

I have installed active sync 4.1 but get just the same. Any thoughts before I go back to wm2003?

A bit more information - if I add files to the sync list when it fails it says Windows PC attention reqiuiredand if I click on that it says Files: Attention required - but nothing to say what kind of attention! Really helpful!!
