Hello! I got my GB-580 today and I am having a bit of trouble with the Training Gym Pro software that came with the device.
When I first installed and opened up the program it worked great, until I tried to save a file uploaded from the GPS.
I got this message:

When I saved the GPS data as a KML file it worked fine, but when I tried saving it as a GPX file I got the above error.
I closed the Training Gym software after that and started it again, but I got this error:

I uninstalled the software and installed it again. The first time it opened, but the second time I got the same error. Does anyone know what I am doing wrong? Thanks!!
My system specs if needed:
Windows 7 Ultimate 64bit
Intel i7 860 Processor
1 tb Hard Drive
8 GB RAM
Nvidia GTX 550 GFX Card
Is the program compatible with a 64bit system? Or is it something else?
EDIT: Sport Tracks works perfectly with this GPS, I just want to know if I can use this software as well.
