OK... so far I've found version updates to the HACtronic software as well as the CicloTour software.

Open both programs on your pc. Click Help-About *** and write down the versios of both software packages.

If you aren't at the following go to the Ciclosport download page and download the updates. Make sure that you download all the instruction files as well.

HACtronic version 1.51 build 50
CicloTour version 1.31

the site for downloads is:

There isn't a "troubleshooting" index on the site (or I haven't found it yet, but I'm checking other sources.
