Uploaded MIB shows as Undefined in MIB Browser

I uploaded a MIB I downloaded from APC's web site. I uploaded it into OpManager. Now when I select it in the MIB Browser list, it does not show the MIB tree. It only shows the word "undefined".

Anyone seen this or have any ideas? Sounds like a problem with the structure of the MIB file.
