O.k - first I'm sorry - I was using by mistake ver 2.0.1.0. on ver 2.0.1.1 the problem is gone using the english report.
However - I tried again to replace the layercalendar.js and calendarevents.js files in my standalone skin with the sames files from the latest Narrative Report skin (ver 2.0.1.1) but I get this error message and non of the events are dispalyed.
I hope that you could fix also the stand alone version on that matter.
Thank you
