**FIXED**
Well after much adieu, I opted to uninstall Workstation 9.0.1 and reinstall using my 9.0.0
installer file. Once I was in 9.0.0 I launched a VM which gave me the dialog about needing to update
tools. Oddly, it updated the entire Workstation to 9.0.1. Once it finished I launched a VM again,
I again received the unable to update tools dialog. Undaunted, I clicked it again, it failed again, so
I clicked it again. Finally it says, nothing to do. Odd. In any case it seems all is well again, my VM has
networking and sound which were both in a broken state.
