Autodesk Revit Architecture

[#1]

Hi.

When I'm trying to edit my surface / topography and I'm done and clicking the green button an error message displays on the screen as the attachment below shows. This happens every time, but only on this particular PC. On my laptop at home this is not a problem.

I've allready tried to reinstall Revit without any luck.

Anyone who has experienced the same problem? If so, any tips? This is really annoying.

I C U R A student? Is there a possibility of moving to another workstation?

But thanks anyways.
