Opencities Map Advanced & Bing Maps

Have an issue with Bing maps & Opencities Map Advanced. I have a DGN file which has Bing Maps raster attached. I can bring this file up in V8i and Bing Maps displays with no issue. However, when I open this file in Opencities Map Advanced, the raster will not display until I perform an update. Is there a setting in Opencities that I have failed to address?
