Hi Jules,
I'm Craig, an Independent Advisor and I'll do my best to help you today. Have you tried to check in your Acrobat file first:
Goto EDIT -> PREFERENCES...
On the GENERAL Category.
UNCHECK the 'Enable Protected Mode at startup'
Then go back into EXCEL & check if it works?
Please let me know if you need further assistance.
Regards,
Craig.
