Problems importing OLM files to Outlook on new MBP

Looking for some help. I recently refreshed to a new retina MBP running OSX Mountain Lion from a previous MBP running OSX Lion. The new machine came preloaded with all the apps I needed and all I want to do is move local email folders in 'on my computer' to the new one. I proceeded to highlight the folder in question and then did a File-->Export to an .OLM file. The procedure worked (took a long time for 13Gig of data). Then I copied the OLM file to portable drive and then tried to File-->Import the .OLM file into Outlook on the new machine. Every time I tried to use the import function Outlook crashes.
