Flow accumulation

Hi,
I'm running ArcGIS 10, and am trying to create watersheds using newly available LiDAR for my area.  I have a flow direction raster that I've clipped to reduce the size (520MB), and have attempted to create a flow accumulation grid.  I have let it process for days, and the banner at the bottom still scrolls Flow Accumulation...Flow Accumulation...  There is no indication of progress (%).   I don't know if it's actually processing or not.  I have tried this several times now.  Any suggestions?  This is the first of a dozen similar size or larger areas I'll be trying to run.

Thank you,
Karyn
