raster combine error

I am using the raster Combine tool within Model Builder in ArcMap 10.0.  This worked well for a number of runs, but now I get the error messages:

ERROR 010158: Unable to open file c:\progra~1\arcgis\deskto~1.0\bin\tmp0365.
ERROR 010067: Error in executing grid expression.

This happens even when combining rasters that successfully combined earlier.  Any clues about a fix?
