Problems with virtual com ports

Hi,

I am working with an xp machine and the Logitech cordless desktop mx for
bluetooth. I was syncing my Motorola v525 via bluetooth using TrueSync from
Starfish. But since one week it isn´t possible anymore to establish a
connection to the mobile phone via the virtual comports. OBEX file transfere
and OBEX object push works still fine. I hope you can help me with my
problem.
