Hello all,
I think the problem is in my own computer. I ran the sfc utility from cmd (scans and repairs .NET 2 and 3 files) and it said it found corrupted files and failed to fix some of them. So yes, solution to that will be to rebuild my machine.
Also, I've managed to completely avoid using the dll by rewriting everything into LabView directly (thank god for the Formula Node...) so problem solved (in a way...) !
