Problem with Sculpting in relation to UV Unwrap

Unfortunately I am experiencing an urgent problem in regards to creating a UV Texture on a Multiresolution modified sculpted mesh. When I attempt to create the prior mentioned UV Texture a majority of the time Blender crashes, and when this does not occur and I am able to Unwrap the mesh the sculpting data is completely disregarded, and Multiresolution now acts as a Subdivision surface modifier to the mesh. Please provide a solution to the problem outlined above. Below I have included some screenshots:

Need a better screenshot with the faces selected in edit mode -I cannot tell from your screen there what resolution the faces are projecting at, or even your unwrapping method.
