Report Hoster 5.00 Problems

[Telecaster]

I dont know if im in the right place for this so move it if you must...
I just purchased an Alienware MX11 Netbook with an I 7 Processor,a 500 gig hard drive,and 8 Gigs of ram ,running Windows 7.
I downloaded the Demo version of Hoster to see how it would work.
IT DOESN'T work.As soon as I go to play a zip file it will let me start the song ....it plays .....there is no video...and the program freezes but the song still plays...then when I try to control the program it locks up totally.The Alienware netbook also has the NVIDIA card in it but I dont know what to use in its place for drivers.
Please help if someone can as if I cant get the progam working right i will be sending the Alienware MX 11 back *:(
Hoster Lite works on my other netbook.
Thanks
Dan
