Crash of Standalone solver

Hello.

I have a bug with "batch run->My computer" in Floworks 2008 (and Solidworks 2008)

Solving with : "Solve->Run->Current Session" works perfectly
Solving with : "Solve->Batch run->Only Create Mesh->My computer" works perfectly

But when I try to solve with "Solve->Batch Run->Create Mesh+Solver->My computer" the mesh generation works but then, the solver crash and the Status in the Batch Run table indicates me an error of calculation

This problem occurs with all simulations.

What is the origin of this problem and how can I solve it ?

Thanks .
