hoster will not down load karaoke

[RICHHOPPY]

I had my computer up graded to a320 G Hard Drive and know it won't recoginze the down load in the file it use to down load in., Also in my home computer the mother board got hit and had to have it replaced. They did not pick up my Microstudio or Hoster so i tried to re load and it will not let me load because they say i have already got it on two computers.
