You obviously have Numbers 3.0.1 running. Are you opening the file by using File/Open or some other method?

I've tried opening it - File/Open from within the application as well as Right Click/Open with/Numbers 3.0.1 from Finder. Both of them resulted in an error message. I've created and saved a couple of new spreadsheets since then and all of them have opened without any problem, that's why I was wondering whether you think it might be a problem with the file itself?

Sounds like something is wrong with that file. Strange choice of error message, though.

Yes, I thought that the error message in that context was odd as well.
Thanks for your help anyway.

Hi, if your file is synced with Google Drive or Dropbox then this might help you.

The file was in fact stored in my local Google Drive folder. I followed the steps noted in your thread and it opened up perfectly.
Thanks so much for your help.

I had a similar problem: ' need newer version'!
In fact som Numbers files opened OK - while others required 'newer version'(?)
The reason turned out to be that I had two versions of the Numbers app on the Mac: When you download version 3.0.1 the previous version (2.3 in my case) seems to remain untouched in the App Folder!
Apparently, some of my files have been formatted for '2.3', others for '3.0.1' - and they must be opened in the appropriate App!
I find this somewhat confusing, since I would normally expect newer versions to replace the existing one(?).

The 'need a newer version' error is being caused by various errors, not all particularly related to the version of numbers you might have. So it's not a very descriptive or useful error message in some circumstances, even though sometimes it's being caused initially by third party software like dropbox and google drive.
I have both numbers 2.3 and 3 on my mac, but one is not an update of the other. Version 3 is I believe a restart for the numbers software, better compliant with osx and ios alike with a focus on sharing and usage across devices. Since it's a restart there are fewer functions and capabilities for now which is why the upgrade didn't replace 2.3. The older and in many ways more complete version 2.3 remains on your mac if you want or need to use it with your existing spreadsheets.
The same is true of pages and other iWork and iLife apps.

that clarifies matters. For me the confusion started when I moved a file from iCloud to my Mac - I was then prompted to reformat the file to a newer format (or something to that effect).
When subsequently I attempted to reopen the file via '2.3' I received the 'need a newer version' notification.
For me the best solution now seems to be retaining both versions (for a while at least), keep my existing files in 'old version', and create new files in version 3(?).
