Question about Outlook Express

Using MS Office for Mac 2011 via a volume license purchased by my employer.  Recently retired and no longer on the employer's Exchange server now.  After a hard drive crash, I replaced my traditional HD with a solid state drive and reloaded MS Office for Mac 2011 from the original install CD.  Everything works well except for Outlook; the initial navigation pane will notl open whenI start up Outlook, no matter what I do. The toolbar prompt for a new main viewing window doesn't produce anything either--no response from my machine.  Have downloaded and installed version MS Office 2011 Mac 14.2.4 and am using Mac OS X 10.6.8 on a 2007 iMac with 1gb memory total and a 200mhz Intel CPU.  Fortunately, I had saved all of my Outlook data when I suspected the original hard drive problem.  Used the export function and saved the data from the original hard drive to a flash drive.  Have imported them to the new SS drive, but no response from the my computer to view my calendar and contacts data.  Calendar reminders still work and pop up correctly on my screen.  I can enter a new appointment on a separate screen, but I'd like to be able to see my monthly calendar all on one screen.  What am I missing?  Help please.
