Spatial Analyst tools

For something I am working on I went to Spatial Analyst tools.

Spatial Analyst tools-Hydrology-Flow Direction

I put my raster/dem into flow direction and have got an error message every time. The only time I got Flow Direction to work is when nothing showed up on the screen except my raster/dem blinked on the screen then disappeared.

Note that in order to make certain tools work, you might need to go to Customize- Extensions...then check the necessary extensions to make the tool work.

Any way, I would like to know how to get past this error message.
