I am trying to import requirements from MS Word into Test Director.

I did install the add-in and also tested a test doc import into TD and all worked fine.
However when I tried to import the actual document (that is 71 pages long) I got the following error:

“Overflow. Cancel and please try again.” In Test Director Export Wizard. I have tried it numerous times but no luck.

Could someone provide some help since I am stuck?
