Hello again,

After a bit of digging I found that this is likely caused by a bug in the
current TPP compiled and distributed version of Kojak that will have to be
corrected for the next release.  Meanwhile you should be able to download
and use the official Kojak build available here:
https://kojak-ms.systemsbiology.net/download.html


This version will require additional .net dependecies!

Please replace the current kojak executable in c:/TPP/bin with the
executable from the zip file and try running kojak again.


Best of luck and keep us posted to your progress.

-David
