The final release of V3.0.9 is now out. This release contains a couple of bug fixes for downloading from Polar FT80 and RS300x devices, and a fix for a crash that can occur if the preferences file becomes corrupt.
You should be prompted to download the latest version when iSMARTtrain starts, or you can download it from http://www.ismarttrain.com/downloads.php.
Any problems/questions, etc., please post in the forums.
