Files not opening

My project file opens fine, but when I click ‘Import File’ and select the file I want, nothing happens. The window that says ‘Fit image to camera width’ etc. doesn’t show up either. just nothing. I tried rebooting toon boom and restarting my computer, but it didn’t help. This problem just started today. Can anyone help? ???

The file that you’re importing, is it in a supported format?
