Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
To make sure, are you using Aperture ?
We have two options in here. If you want, I can remotely connect to your Mac and fix the issue myself for you while you watch. This is an optional additional service.
Or I can give you instructions in here. So you can follow them to solve the issue. Which one do you prefer ?
Are you using Aperture application ?
What version of Mac OS X are you using ?
