I'm sorry about the issue. When did this issue first occur?
Is there any error or message?
What's your Mac OS X version, i.e., 2003, 2007, 2010, 2013, etc.?
Do you have windows xp, vista, or 7, or 8, 10?
Can we do a remote support session, so I can troubleshoot the issue directly on your computer together with you?
Please reply at the box below. Thank you,
What's your Microsoft Office version, i.e., 2003, 2007, 2010, 2013, etc.?
