Hello to all. I am a new member in you community. I am trying to make a smulation analysis in solidworks 2015 and after editing the fixtures and the loads and creating the mesh, when I am trying to run the study the following message appears: Unable to open master control file.To define problem name, use characters supported by O.S..Do you have any idea about the reason for this problem, amd the solution i may find?

Thank you very much in advance.
