Problems with Flow accumulation tool

I'm still having problems with Flow Accumulation tool in Hydrology/Spatial Analyst.
Arcmap shows work in progress (It says: "Updating flow accumulation..."), however it never ends. I've tried with Arcmap 9.3, Arcmap 10.
I just created a new raster of flow direction, in the case the previous I used was corrupted, but the problem still: the process never ends and I have to stop it (last time it was done was during a whole weekend). I've donde same process for other regions and it worked very well, this situation just started to occur a couple of weeks ago.
I'm very concern whether something is wrong with my data (license and extensions are checked, and ok) or it is something happening with the tool and there is a solution (patch, or similar from ESRI).

please, all help will be very appreciated.
