no internet and no "bin" files?

http://forums.fedoraforum.org – I just upgraded my Win8.1 machine to Centos 6.4, and have another Centos machine running in VMWare. Everything worked fine before the upgrade on the host machine, but now I can't seem to get to the internet from the Centos VM. I can get to other local machines (both host and VM), but I have no internet access. I cannot even run certain commands from the command line (as a user or as root, through "su"). I can run some commands (like "ls", "cd", and stuff), but I cannot run other commands, like "ifconfig", "service", and the like. EVEN (HowTos)
