Error in executing grid expression - Reclassify

FIrst of all i'm a novice to ArcGIS and i'm attempting to get shortest paths between ports over the ocean (globall located ports). The easiest way i can see of doing this is to
1: COnvert ocean feature dataset to raster
2: Reclassify so the whole ocean has a value of 1
3: Run cost distance against all ports
4: Run cost path against all port

HOwever, i'm hitting a problem at point and getting the following error when i try to reclassify:

Executing (Reclassify (2)): Reclassify D:\PHD\Modelling\GIS_Modelling\NetworkModelling\ocean_raster Value "57211527168 11152826302464 1" C:\tmp DATA
Start Time: Wed Feb 09 09:09:32 2011
ERROR 010067: Error in executing grid expression.
Failed to execute (Reclassify (2)).
End Time: Wed Feb 09 09:09:33 2011 (Elapsed Time: 1.00 seconds)

Incidentally, I'm doing this through model builder (i've tried running each function separately as well as running the entire model). I've looked up what typically causes this and found it's spaces or if the raster file name output is greater than 13. But neither seem to be the case for the above. Is there some issue that the values are too large to reclassify?

Apologies if this has been answered somewhere, i haven't been able to find it.

Thanks for any help/advice
