--- Comment #3 from Ulrich Gemkow ulrich.gemkow@ikr.uni-stuttgart.de --- Thanks for looking into this! Unfortunately a free demo is no longer downloadable. I have a installation file which is the same as the demo version as long as no serial number is entered. But distributing this is not allowed per the license. I can provide it when really required (but installing is not trivial).
But the demo is also not very helpful. The program crashes with a dialog box saying (rough translation) "The program deteced a serious error and must be terminated" and then terminates mostly regulary.
In previous regressions of this kind the log files helped showing exceptions or pointing to the right problem.
Hopefully the bisect or more log files helps finding the right solution.
