Hoster not working, need help ASAP

[Ernie]

On my laptop I went to open Hoster 4.06.... and nothing, just a blank screen. I tried it two more times, same thing. rebooted... same thing. I then blew it away and reinstalled it. It opens with brown screen and large letters.. Hoster by MTU, then goes to dark screen. I've never had any trouble with Hoster or Laptop before. I only use the laptop for hoster. I have HP Pavilion 17", XP Home edition, two gigs of ram.

Thanks,
Ernie
