Amey,
It seems the flipchart is corrupt. Not sure what may have caused that but clear the temp files, empty the recycle bin and restart the computer. Some files may not allow you to delete them because they are necessary for other programs to work. Please ensure that Java 6 is up to date and Adobe Flash 11 is also up to date. Did the teacher just install the latest version or did they simply update it from a previous version? In what location are they attempting to save the flipchart? (case# 235077)
Thanks!
