Problems with SMAC and Albedo in SEBS

HC101
Are there any known issues with generating SMAC and Albedo from MODIS Level 1B ?

Over the last few days I've had issues with computing SMAC for the 6 bands required:

1. After trying many images at different stages of different years it seems to be a problem with the Geolocation files given by MODIS  - ( SZA , SAA , VZA , VAA )

2. Even when I don't insert the rasters for SZA, SAA etc. and keep the values constant to generate the SMAC images, generating Albedo will not work.

Am I missing something obvious or are there any know issues with these processes?

I will forward this to the person who implemented SEBS in the past. Maybe she has some insights.
