And are you running abootleg version of winXP? becuase there was a key that was used a long time with bootleg XP disks that does not allow the user to download the winXP SP1, and if you do not have Service pack 1 then you cant suport java or anything of the such. you are going to have to dl the microsoft VM java application individualy from the service pack somehow.
And try upgradeing your media player thourgh the windows update site.
