Outlook Mac 14.5.0 Mac 2011 opens but can’t see home page

Hi

<MS Outlook 2010 v14.5.0 (up to date) for Mac with Yosemite OS on MacBook Air>  NOTE I HAVE MS OUTLOOK 2010 NOT '2011' 

When opening Outlook, the programme opens but i can't see/get to the home page. The bar with Outlook 'File', 'Edit' 'View' etc options is visible and i can select options such as new message, which works. But the home page is nowhere to be seen.

I've tried...

-Option alt to rebuild several times

-Deleting from library/preferences the 'microsoftpreferences file' - had to re-enter security key

Suspect it's a preferences setting somewhere in Mac OS or Outlook but could be a corruption somewhere. 

All other MS apps work fine (Office, Excel)

I saw the 2012 thread on this issue noting solutions above but no joy.

Really don't want to re-install Office.

Any suggestions?
