413.1 Error (Request Entity Too Large) importing data

I keep getting a 413.1 Error (Request Entity Too Large) when importing data in the Admin, Tools section.  I've increased the limit in applicationhost.config and set maxRequestEntityAllow and uploadReadAheadSize to 2147483647, the max value.  I've restarted the site multiple times.  I can't get dev and stage data synced with production w/o being able to do this step.  What else can I look at?

Thanks,

Tim
