Graham,

Thanks. But I found the error (after hours of trial and error). My source table contained a "Enter/Return" in the paragraph, which caused the file to become corrupt. From what I gathered online contentcontrol don't handle the "Enter/Return" key too well.

Example:
Some text, some text.
Goes here.

I changed it to one paragraph > Some text, some text. Goes here.

Now when I save my document and try to reopen it, I no longer receive the error.

Does your macro address the "Enter/Return" characters?
