Hello, I am attempting to make a simple calculation with the Raster Calculator in ArcMap 10.  I successfully carried out the same exact calculation yesterday using the exact same formula, so not sure what the problem is.  The calculation is: "ndvi_08_06"  > 0.5, which will give me all cell values classified as .5 or greater.  This worked fine yesterday, but when I tried it today on the same dataset it returned this error: "ERROR 000539: Error running expression: rcexec() <type 'exceptions.RuntimeError'>: ERROR 010240: Could not save raster dataset to C:\FileLocation\Output\raster5 with output format GRID."  When I went into the Geoprocessing results window and reran the expression form yesterday, it just returned a solid grey result.  If anyone has any ideas, I would greatly appreciate it.
