My mistake, the command is "vxconf". Still, vasm should have gotten you there.
Sounds like your installation is incomplete and probably not recoverable. Problem may be either a corrupt download, or a bad burn, as flip city suggested.
To test your download, follow the instructions here: http://www.openoffice.org/dev_docs/using_md5sums.html
I'd recommend scrolling down to the command line option, but either way is fine.
If the iso file is okay, burn again, but look for a "speed" option on the burn page of Roxio. It is usually a drop-down menu that defaults to "Max". Change it to 8 or lower.
