My thoughts:
I have the correct verbyte, right? (0xD1 / 209d)

It worked before, and it works on WarCraft III / Diablo II (so its obviously something to do with the #region Lockdown).

The parameters for the function are read right out of the BncsReader:
SendPacket51(a_prReader.ReadInt32(), a_prReader.ReadInt32(), a_prReader.ReadInt32(), a_prReader.ReadInt64(), a_prReader.ReadCString(), a_prReader.ReadCString());

The problem you're running into is here:

[code]
m_pbBncsPacket.InsertCString(m_sExeStatstring);
[/code]

Instead, use the InsertByteArray method and store the Lockdown results as a byte[], not a string.  .NET cannot convert between a byte[] and a string the way you're trying to do it (which is why MBNCSUtil returns a byte[].  I didn't just do it for shits and giggles).

Suggested code to replace this:
[code]
m_pbBncsPacket.InsertByteArray(m_bExeStatstring);
m_pbBncsPacket.InsertByte(0);
[/code]

Also, drop this section:
[code]
                foreach (byte m_bExeByte in m_bExeStatstring)
                {
                    m_sExeStatstring += (char) m_bExeByte;
                }
[/code]
It doesn't work correctly for you.

Can you show me how you populate your g_bVersionFormula variable?

Also, I've noticed that you've got a couple other difficulties -- for instance, you try to convert the val string to a string in a way that isn't really good.

This is my latest code that I use for handling 0x50 and sending 0x51.

[code]
        private void HandleAuthInfo(DataReader dr)
        {
            if (m_pingPck != null)
            {
                Send(m_pingPck);
                m_pingPck = null;
                m_received0x50 = false;
            }
            m_received0x50 = true;

            m_loginType = dr.ReadUInt32();
            m_srvToken = dr.ReadUInt32();
            m_udpVal = dr.ReadUInt32();
            m_mpqFiletime = dr.ReadInt64();
            m_verFilename = dr.ReadCString();
            m_usingLockdown = m_verFilename.ToLower().StartsWith("lockdown");

            int crResult = -1, exeVer = -1;
            string exeInfo = null;

            // not using lockdown
            if (!m_usingLockdown)
            {
                m_valString = dr.ReadCString();
                int mpqNum = CheckRevision.ExtractMPQNumber(m_verFilename);
                crResult = CheckRevision.DoCheckRevision(m_valString, new string[] { settings.GameExe, settings.GameFile2, settings.GameFile3 }, mpqNum);
                exeVer = CheckRevision.GetExeInfo(settings.GameExe, out exeInfo);
            }
            else // use lockdown.
            {
                // get the value string as a NT byte-array.

Can you show me how you populate your g_bVersionFormula variable?[/quote]Yay! I fixed it.

I made it use .ReadNullTerminatedByteArray() to get the value string, rather than .ReadCString() and a crude loop. :/
I don't know how WarCraft III worked with the other way.  Probably because the lockdown value strings are reallly weird "û.uÄÍ>1.¸'.Rãi.M" while the others are simpler "C=3779699026 B=4034163727 A=3366429739 4 A=A+S B=B+C C=C+A A=A+B".
Well um, resolved. :)
