When I am trying to sync some songs in wma format that I got from Puretracks from a WinXP box with WMP 10 with my Axim X30 upgraded to include WMP 10 I get this error message:
"Error: Windows Media Player cannot play the protected file because the required security upgrade is not available for download."

The files play fine on the computer and I installed some security update for WMP 10 that I found at Windows Media Mobile FAQ
