SRP6 in C# w/o OpenSSL

[Kaev]

Hiho,
atm i'm developing a logon server for learning purposes.
Sadly i stuck at the SRP-6 part, which i want to do without using OpenSSL, and i can't find my mistake.
I think i'm calculating something wrong, because my calculated MS is never the same as the client calculated M1.
Here's my SRP class: [C#] SRP.cs - Pastebin.com
Here are the important parts of my OpCodeHandler class: [C#] Parts of OpCodeHandler.cs - Pastebin.com

I can also upload my whole solution if someone wants to debug it.
You're my last hope.

Shameless bump
I found this: https://code.google.com/p/m-client/s.../Crypt/Srp6.cs
Calculations are looking like mine.. :/

EDIT: Oups, i think i do the client calculation at the end instead of the server calculation. Changed that in my local code, still not correct. :/
EDIT2: Updated the code in the pastebin. Fixed some things, sadly still something wrong.

You were well on your way, however you made some common misstakes. I have pointed them out right in your source and re-pasted it here.
By the way - M1 and M2 will never match; they're two very different things.
