Another possibility for not responding to emails:
TIVUS is not allowed to talk about any contract they may be negotiating in as a matter of standard business practices of publicly traded companies.
Perhaps TIVUS is very close to updating us anyways, hopefully on several different things. The update, if it is good news - the CEO doesn't feel it is necessary because of this and maybe too, he hasn't liked all of the criticism he has received and so he is doing no favors for any investor that isn't in this for true investment purposes.
