Edit: 6.0.22 (Update 1) has been released, so this is not necessary anymore.
For those who have updated their Mares Genius Firmware recently to version 01.02. need to download an updated libdivecomputer version. Download this file and copy it into the Diving Log 6.0 program folder, otherwise the downloaded dives have incorrect data.
The next Diving Log update will include this file, but if you have Diving Log 6.0.22 or older, you need this update for now.
