Cant close an Omnigraffle trial version document - help
 

Hi, I can't seem to close down a document made some time ago in Omnigraffle - a trial version and because of this it will not allow me to shutdown or restart my computer. I have an MackBook Pro. A window appears with three options. "licenses", "Use Unlicensed" and "Buy license". The Buy license option is highlighted and flashing but all three options are unresponsive. All tabs in the menu are greyed out and nothing is responsive. I cannot close. Please help

Force quit the application. One way to do that is command-option-esc, then click on the app name in the popup window.

Thanks a lot - you can probably tell Im new to the MacBook Pro. Appreciate your help
