Yea check your vmware settings
It has been about two years since I messed with vmware. So unless things have changed please bear with me.
I used to use vmware to run several iso's including linux. There is a file, sorry but I forgot what it is called, which you have to edit to tell vmware where your livcd is located and how which options to initialize including internet access.
I wish I could be more help
