GPS Data Logger Software - BT747

Hi,

I haven't used my Logger for  while. Meanwhile I have Win7 and after I've been on vacation (and used the logger), I try to download the Logs, but with no success. I downloaded the Software and installed everything. After I launch the software, I click at Connect (Port 3 in my case). I see Latidude, Longitude, GPS-Time, The memory usage (48521 waypoints, 97%) everything. So the connection is (in my opinion) succesfull. I click at download and I see the status bar moving. But after it's finnished, I can't find the file. I tried even to use another output directory and another filename, still the same. Is that a known problem? Anybody an idea?
