Having problems importing Windows .evtx logs

Having problems importing Windows .evtx logs

Having issues importing a standard Windows 2008 R2 .evtx log.  I've searched the site and all I see is support asking people to convert from .evt to .evtx, but my logs are already .evtx.
 
So now what?  My cursor sits and says in progress for hours... This log file is only 128MB... What if it's larger?  I think it's a problem.  Any suggestions?
