Arnoldi solver error

Hi,

I am having an error finding eigenvalue of a wave mechanics problem using arnoldisolver. My code was perfectly working earlier but when I reinstalled ngsolve, running arnoldi solver gives following error:

Generate Mesh from spline geometry
Setup and Factorization: PARDISO returned error -3!
err = reordering problem
symmetric = 0
spd = 0
compressed = 1
inner = 0x600000fd47c8
cluster = 0x0

NgException: PardisoInverse: Setup and Factorization failed.

Hope you can help me fix this. Thanks.

Best,
Prasanna
