Structural FEM analysis

Last week I updated Solid works from version 2013 to 2014, but when I now open my simulation model in the new release, all the simulation informations are missing.

The model it self looks ok, but I cannot start a simulation; get the error 'There is no solid body to process'

I have checked a few models (parts), they behave in the same way.

Most of my models are made without any solid bodies, but entirely surfaces and shell elements defined by those surfaces.

For new models, I can work around the problem by using solids, but we need to access our older models for reference.

Q1: How can I import FEM models made in release 2013 to rel 2014 without loosing the simulation info.

Q2: If that is not possible, how can I downgrade my installation to release 2013?

I have enclosed a simple model that has/is the proplem

Best regards,
