I'm using the HAC4 Plus on a PC with Windows XP and the USB HacTronic interface. When I download, both the watch and the PC show that data is being transferred, but then no info shows up in the CicloTrainer screen afterward. CicloTour, andother program just says that there was an error in the program after downloading. HacTronic - the piece of software designed to help download from the watch also show only altitude info on the screen after download. There are absolutely no instructions for any of this so I'm a little lost.

Thanks for the help!
