Paolo, could you please send us MonchaLog.txt file? Please start your Moncha, try to load workspace using File->Load workspace. After you receive error message, close Moncha software and locate that file.
It is located in:
c:\Documents and Settings\YOUR USER NAME\Local Settings\Application Data\Showtacle\Moncha\
Please send it to our company email [email protected].
Thank you,
Michal
