I'm using ver. 10.56 but prior to upgrading, think it may have been 10.55 I also had a problem with the robot. I found the report, instead of saying "single" operator said "le" and I had to edit the file to correct it. I used a text editor, made the correction and resubmitted. Try opening the file with Notepad, make the correction, and see if it will go then. Regards, Dick N0IM
