I used MSOffice 2003. I saved changes as *.HTM

I then used AceFTP to upload the changes to my BT Website. All worked well.

I now have Office 2007. When I try and save a change I get ''may contain
features that are not compatable with Web Page"

If I accept the changes and upload the page will not be displayed!

I know HTM is an old version but does what I want it to do. However I must
have the ability to update my website.

Can anyone advise what I can do to keep the data on my website and be able
to update it.

i.e. Do I need to change all the files to HTML? If so how and how to get
them to be displayed as present on the website. Do I use Office 2007 to
update?

I need to update spreadsheet, and some word docs with photos. I did use
front page but now use SharePoint.

Any assistance so I can update my webist would be much appreciated.
