I get a different number, but the same result. Can't log in. I'll try with 6.2.
Edit: I'm having other (more important) problems on the PC (that have nothing to do with MSNM). So it might take a while for me to post the 6.2 result.
Re-Edit: So, after fighting with my PC, I decided to try again with MSNM7, before installing MSNM6, and I could log in
