if I use the Raster Calculator from Spatial Analyst I get ERROR 000539: (null).

I want to do a simple calculation ("raster" <=164).
In one PC it works, but in an other PC it don't work. Why is that?
I have tested many other calculation and i get the same error. ;-(

I work with ArcInfo 10 and i have the extension Spatial Analyst.

Can anyone help me?
It is urgent.

Many regards.
