Treo Pro and Windows 11

I have a problem syncing my Treo Pro with Media Player 11.

I use my expansion card for music and other media, however the sync function
in MP11 doesn't give me an option to place the files there. It just
synchronizes the files to the device itself, which doesn't have enough memory
to handle music. Is there a fix? Is it there and I'm just not seeing it?
Should I just uninstall MP11 and go back to an older version?

Please help.
