Your post suggest you are trying to import from Word but if so the error message is a bit confusing. Either way, here are some things to try: Regardless of whether you are importing from or exporting to Word, check that you have the same bit versions of both programs - they should be both bit, or both bit. If they are different they won't talk to each other and you will have to upgrade one or the other - presumably MindManager, unless your version of Word is even older. Again regardless of whether you importing or exporting, check the Word template that MM is using.
There is no better time to upgrade for Mindjet Windows customers. Receive all the benefits of the upcoming MindManager at no additional cost when it's launched.
