Looking at the questions and the reviews, it looks like the last Google indexing update did indeed cause their indexing to stop.

I was in denial for a while, I really wanted it to work but it didn't. The product is actually really awesome, if they rehashed it as an indexing tracker (without the indexing because the API no longer works) it would be a solid product and I'd buy again because it was awesome in that function even whent he indexing didn't work.

Unfortunately their lack of replies make me think they gave up.
