Elmer 9.0 version on Windows, errors

[zgrydn]

When I run the codes below in Elmer 9.0 version on Windows, I get errors.

---------------
Solver 2
Exec Solver = Always
Equation = MgDyn2D
Variable = A

Procedure = "MagnetoDynamics2D" "MagnetoDynamics2D"

Nonlinear System Convergence Tolerance = 1.0e-4
Nonlinear System Max Iterations = 30

Linear System Solver = Direct
Linear System Iterative Method = MUMPS
End
--------------------

The error output is as follows. How can I fix the problem? Please help.
