cannot start Inroads...

Inroads: ir081109493en

Microstation: MicroStation_08.11.09.459

Win8-64bit

Since a last crash I cannot start Inroads. I keeps crashing after start-up with messages regarding Microsoft .NET Framework (several times after each other),
WerFault.exe error, Microstation tekst window and several crach reports to Bentley. See some screenshots below.
What is going on? What must I do the get Inroads started.

Please urgent help, Jean.
