If it says build 1017 in the About window - then thats what it is.
Note that our testing showed a different error ("Error while reading file from CD/DVD") is displayed when trying to test the CD that BurnInTest is running from. We assumed (as we could not reproduce your problem) that this may also lead to the error message you received. However, I suspect your problem is something else. In saying this, the file name is written to the log for every case that the error "Could not open file on CD/DVD for reading" can occur. This will not appear on the main window, but on a second line in the detailed error log.
Could you please check the detailed error log. Do you see a line "Error .... file <filename>". Is the File one of yours or a BurnInTest file? (I suspect it is a non-BIT file that is in use).
