Connecting lap top to CAI 302

I realize that the first weekend of June is a little late to take your
first glider flights of the year. Yeah, I missed some great days in
May. Regardless, had two wonderful flights, but can't get my laptop
to connect to the 302. Using the same set up as last year (Dell
Latitude with Windows XP) can't connect with eithe the USB-RS232
adapter or with the straight USB (my 302 has both connectors.) Using
the USB port on the 302, the lap top is looking for the DLP-TXRX.
From what I remember (can't find the paper) the 302 is supposed to
have the necessary software on it when it connects.

I tryed my HP with Windows 7, and same problems. Failed to connect to
the device. Does anyone have any ideas? Moriarty in a week, so I
need to get this resolved.

Or, if anyone can steer me towards a USB-RS232 Driver for windows,
that would be appreciated as well.

Thanks,
Andrew, 3T
