Unfortunately, no - it was the Office 365 version of OneNOte whch proceeded to sync with an old version of my files in the cloud - after a lot of grief I eventually found the backup, but this program refuses to use it and kept re-loading/syncing the older file version. In desparation I went back to the Office 2010 version and whilst getting rid of One Note 365 I inadvertently deleted Office. I re-installed it but then got this issue with Excel.
