Eey ppl

I use wamp for 3/4 months now and i really love it

It's just so easy to use in everything!
but i figured out that some of my scripts just needed php4 so I downloaded the add-on.
after the install I switched to php4, hoping I could use all my scripts now, but then, when i wanted to check my mysql, i couldn't get into phpmyadmin.
so I tried changing some options in the config file of phpmyadmin, but nothing worked.
it keeps saying:
ERROR
-------------------------------
MySQL said:
#1251 - Client doesn't support authentication protocol requested by server; consider upgrading mysql client.
I don't know..
am I doing something wrong here? Or maybe there's a bug somewhere?
anyway, i'm stuck

some help pls
