pardiso C# "not enough memory"

I'm trying to use pardiso in C#, in order to resolve a unsymmetric matrix of complex numbers.

I started executing an example I've found in internet, that works fine.

By the way when I replace the data with others, taken from my examples, it fails at the first step: factorization, with an error related to a memory "-2: not enough memory".

This is obviouslly not possible, because the matrix is quite small. 

I suppose it should be related to some parameter, but there are many and it is possible that I've missed something.

Is there any one that can help me?

I attach the example, the system has 24 equations.

Thank you
