reinstalled from scratch without 9001-ST-Client-FP-AGUA-9GPFKX
I think the problems were caused by the
ST 9.0.0.1 Hotfix.
Reinstalled from scratch without 9001-ST-Client-FP-AGUA-9GPFKX
and 9.0.1 FP1 AllClient German on
Windows 8.1 Enterprise is running stable.
But there are security holes in ST 9.0
again :-(
