Adapative Mesh Refinement with Mapped Distribution

Hello,

I'm using Comsol version 4.3 and, for some reason, when I try to use adaptive mesh refinement in the Stationary Solver's extensions, it claims I can only use triangular mesh elements for it. I need the refinement because I'm working on a project that deals with large deformations. On my other computer which uses 4.2, I can use adaptive mesh refinement with any kind of mesh. Any idea why this is happening or will I only be able to use triangular meshes for mesh refinement.

Thanks in advance,
Rob
