hangs Cubase7.5.30

Hello. Help solve the problem.
I have a program hangs Cubase7.5.30. 64bit when trying to open MIDI Key Editor, Score Editor, Drum Editor, List Editor, In-Place Editor. Operating System PC: Windows7 \ 64.

Hello zam737,

please start Cubase in Safe-Mode:

Does it still crash when opening the Editors?

Regards

Thank you !!! Problem solved through Safe-Mode -“Delete program preferences”. However, what specifically affect programs: not correct the user’s actions (what?) or is trouble developers Steinberg?
