Previously used Visual Studio 2008 and migrated Trajec3D to Visual Studio 2013. The upgrade required a few changes and some things could have been broken in the process. I tested on a few computers and all was good with the testing, but please let me know if you experience any issues as soon as possible. The expiry date for Version 1.6.2.2 is 1 Oct 2014.
