Please help me install a bioinformatic analysis tool

Hello,

I was wondering if anybody could help me install a bioinformatic analysis tool named Chipster. It is a program that uses virtualbox or vmware to install the program as a server in a linux enviroment and then you can run the client through your browser that downloads a java application. I have gotten vmware to work but not virtualbox. I want to get virtualbox to work sodat I can use NAT and remote access the client which the program allows and they have instructions but I am having a hard time following it as it has a great deal of networking jargon which i don't understand. I have been working on this for over 2 weeks with now avail.

Thank you,
