A bugfix update to VNL-ATK 2017 has been released (version 2017.1). Download it from
http://quantumwise.com/products/download.
This update contains a substantial amount of bug fixes, in particular several that fix various crashes. We are not aware of any bugs (solved or not) that would cause decidedly wrong results or errors in calculations (except very minor ones), but there were quite a few scenarios in which ATK 2017.0 would crash. The new 2D plot framework also received a touch-up in this release, and we spent some time solving minor annoying issues in VNL to improve the user experience.
