FEM study "STAR"-error

I've created an assembly made up from a number of parts, fixed some points, and put some forces on, in order to make a FEM study.

Then i've created a H-adaptive mesh, which seems to work fine.

When i then press "Run" to make the analysis, i get an error message, saying "STAR stopped working", and then i can do nothing but close the program "STAR", whatever that is.

Then i get the error message "Database not found", and the FEM study failed..

Does anyone know, what causes this problem, and how to avoid it?

I'm using SolidWorks 2010-11 SP 3.1, educational version | Windows 7 Professional 32-bit | Lenovo T500 |
