Thanks Niek,

The exact message is: "File Error: Data may have been lost" and this message
appears 5 seconds into opening the file. Then Excel continues opening and the
file appears eventually. I do not know which data is lost by the way. I also
have seen other problems (all hyperlinks that are placed on buttons; used to
navigate from one page to the other or from one section to another; all these
links have become uneditable images that cannot be erased or moved).
Evidently I do have a legal copy of the Beta but finding how to reach anyone
at Microsoft is way too time consuming for me and of a complexity that only
Kafka could have imagined.

Best regards

If you have a legal copy of the Beta you should be aware of the sites that are meant to report problems.
I can imagine the developers would be glad to receive somewhat more specific descriptions of your problem than "experiencing
errors"
