problem with MySqlClient

Snips out of my program are:
#using "ByteFX.MySqlClient.dll"
using namespace ByteFX::Data::MySqlClient;

m_DbMySqConnection = gcnew MySqlConnection( conn1);
m_DbMySqConnection->Open(); // Open up the connection

where conn1 is like:
Database=harrington;Data Source=10.0.2.2;User Id=fiji;Password=***;
(password has the actual value, not duplicated here.)
I am using Virtualbox on Ubuntu 10.10 to host XP in a Virtualbox, and thus the data source points back to the Ubuntu host.

When it tries to open I get the error message:
Client does not support authentication protocol requested
by server; consider upgrading MySQL client

This is explained in the documentation as:
MySQL 5.5 uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older (pre-4.1) clients.

My question is why ByteFX is so old and how can I upgrade it? Likewise do I have any other choices other than ByteFX? Could I somehow use
#using "MySql.MySqlClient.dll"
using namespace MySql::Data::MySqlClient;

and if so, HOW???

I should mention that I also have a Java program accessing the same MySQL database. The Java program works with no problems, which is one reason I wanted to update the old c++ program.

Thanks,
Ilan
