DirectEntry error

I am using DirectEntry for the first time. When I change the scale in the DirectEntry from .05 to something like (0.1, 0, 0.05), I get this error:

:linmath(warning): Tried to invert singular LMatrix3.

Is this a bug in 1.5.2?
I haven’t been by my friend yet to get the update, so I am still using 1.5.2

Don’t put 0 in for a scale. Use (0.1, 0.1, 0.05) instead.

Thanks a lot
