Jerry came by and fixed the issue with the grinder pump. It turned out that the darn pump float was sticking. He said once and a while tissue or whatever gets stuck on it and you have to giggle it. He showed me where to take the cap off and shined a flashlight on it for me to see where the float was. He told me that if it ever happens again, try that first and chances are, that'll do it.
We flushed the toilet a couple of times and made sure it worked. It did.... problem solved. I was so relieved that it turned out to be something that simple.
