Conversion-Error from v8 to v9 (Linux and Windows)

Hello,
I just installed SC9 and updated SC9. Then I tried to convert my projects form v8 to v9 following the instruction (text and video). SC display a list of converted tables and so on - no error-messages. But the view of projetcs is empty - even if I restart SC.
I take a look at /scriptcase/log/conv_V9_erro.txt (this file is about 8 MB). There are a lot of lines like this:

  • Inicio: 18/09/2017 04:51:07

  • Error

Then I installed SC9 on Windows 10 64bit: the same behavior.

Has someone a hint how I can resolve the problem?

Thanx

Has nobody an idea?
