It looks like I was right when I said that there was no way to save Star Trek Enterprise by paying for it (See: Fans Attempting to Pay for Enterprise).
STARTREK.COM
We can not and will not be able to accept funds from viewers to produce Star Trek: Enterprise or any other series.
The only way to save this show is to prove that it is viable for the advertisers who are purchasing commercial time on the program. Forget a letter writing campaign to Paramount, send your letters to the advertisers. Let them know you love the show, explain to them that their add dollars have gone to good use and that you are buying their products.
