Purchased and downloaded FM 11. Tried to use the tutorials but FM returned a dialog box saying "files were missing" and that I should reinstall the software. I don't know what to 'reinstall' since I don't have disks.
When you downloaded FileMaker, you downloaded an installer program that you had to run to install filemaker. You should just need to run the installer again. The tutorial files are supposed to be installed into the English Extras folder.
