Last Saturday 13-12-2014 Advance Design 2015 SP1 stopped working.
Nothing was made to hardware, installed just Windows 7 x64, Microsoft Office 2013 x64, AutoCAD 2015 with Advance Steel 2015.1 and nothing else.
Attached are screenshots made during startuop hang.
Advance Design 2015 (without SP1) is starting without any problems.
