Hi,
Version 4.0.9 with Suunto downloader v2.9.5.12 was importing the temperature data (air/water) successfully.
I downloaded the new 4.0.10 version with Suunto downloader v2.9.7.1 and doesn’t get any temperature data.
The SuuntoXML.xml is being every time created successfully and includes the temperature data.
Thank you for the hint! You're right, the watertemperature is currently only imported for the newer computers where it is recorded in the profile, I forgot these values. I'll add this in the next update again. In the meantime you find the old downloader which imports the temperature in the menu "File > Import > Suunto transfer" (without the .NET 2.0).
