Track download from GT-600 fails with errors

[Jan-Gerard]

Connecting to the GT-600 fails many times, but when the iGotU is recognized, I get an error message and no track.
When issuing the command: igotu2gpx.exe -v -d serial:4 dump
this is te response: >>>>

Meanwhile, I made a log of the serial port with sysinternals/portmon.exe: >>>>

It seems like the igotu does not respond at all to this command. It is connected, however, because I once got this response: >>>>

It started downloading a block of data, but failed.
Do I have to set serial port settings of the virtual com port, like baudrate, etc?

Kind regards,

Maybe this can help to identify the issue.

I am sorry, I forgot to mention that I am running XP SP3.
