You're certainly welcome!
I've used the Media sync functionality on the X51v, and found it to be cumbersome at best. A much easier method of transfer of media files to your PPC is to disable the media sync function (Activesync Tools-->Options-->Media uncheck) and manually copy the files to your storage (ROM or expansion card).
When I used the media sync option, I had the same "Setup must be completed" error problem as you. The process worked but Activesync thought it didn't... Eliminate the media sync factor from the equation and DIY, faster and better.
