1) Did you enable NAT or Bridged Networking for the VM (If it's a silly question please ignore).
2) Do you have any Networking (either Wireless or Wired) working on the Host and enabled -- If there's no HOST networking enabled AND WORKING you can't enable the VMware Nic. (The Host doesn't have to be connected to the Internet but the Network card MUST BE ACTIVE and WORKING even if you choose Host Only Networking for the VM).
Ensure also VMware tools is installed -- I've never run into Networking problems on a VM -- on the Host yes many times !!!.
