You can download a file converter for free from Microsoft. Look in the lower right corner for the link. Sorry I can't seem to find a direct link for it. If you can't do the install yourself, place a work order for a tech to do it.
The format is not really new- it's been out for a while.
I've been quite frustrated with the way Pinnacle works on my Mac. I can't use enter to move from entry to entry (10 key). As a lark, I tried FireFox- problem solved! I can ten key to my hearts content! Ms. Head would be proud! She was my "typing" teacher in HS ; )
