Bug with INVALID STAR RESIDUAL FILE after aRestart

Hello everybody! I have a bug in Star-cd (one more time...): After an Analys Restart, I want to see the residuals with the Run History of Previous Analysis. I can see it after few iterations, but when there is at least 10 iterations done, The graphs don't appear anymore.The written message in Star Output is:

**ERROR - INVALID FILE case.rsi CHOSEN.

FORMAT DOES NOT CORRESPOND TO STAR RESIDUAL FILE.

Then, if I do a Restart again, I can see the graphs for about 10 iterations, and not anymore later... If you know what to do in order to avoid to do a Restart each time, please, answer me!

Re: Bug with INVALID STAR RESIDUAL FILE after aRes

Thank you for the speed of your answer Jörn. I read the old mails corresponding to my problem, but when you said "You need Perl and gnuplot to use the script", where can I find Perl and gnuplot?
