Maxsurf Extrude Surface Error - any solutions?

I have modelled curves and would like to extrude those curves. Once I try to do so and specify the vector (as 2,0,0; modelling in Body Plan; Extruding in Perspective) I receive the following error and it iterates once I click ok: Please set a non zero value

Eroor

I am using Maxsurf modeller Connect Edition (Advanced) x64 (22.00.00.97). 

Any ideas?
