I am using Excel 2007 and have been experimenting with macros and VBA,
including the Personal.xlsb file. Now, every time I open Excel:
1. it tells me the Personal.xlsb file is locked and do I want to read only,
be notified when its closed, or cancel
2. I can't open Excel files from Outlook and some my previously functional
addin applications now don't work.

Now do I reset the personal.xlsb file to its original state? Is this the way
to fix the problem? If not, what is?
