dialogue window says file can not be found
I changed the name of a file, and when I click it to open it a dialogue window opens up saying "file can not be found" (showing old file name). But when I click cancel the file opens opens up with the new file name. How can I stop the window from opening up each time?
I am using FMP 9 an I have a mac running os 10.5.8
Thank you for you help
