Have you done the Acrobat updates (currently 11.0.04)?
Yes, I have. I have already stated I did in my original post.
I've been having the same issue for about two month's now. The pdf file does get created, but Word crashes and has to reload. Currently running Acrobat 11.0.05. Word Version 14.0.7106 32-Bit.
I'm still suffering the same issue. I am also running Word 2010 SP2.
My brother installed on his system which is Windows 7, Office 2010 and it works fine.
I have now gone back to Actobat X and it's working.
The issue doesn't occur in Windows 8 or Windows 8.1.
Adobe have not been helpful at all. I am seriously getting the mind of asking for my money back.
Mine magically started working last week. Still running Acrobat 11.05 and Word 14.0.7106. Something must have done an update and fixed the problem.
