We have worked with a few cows that could not be AI'd. There are many reasons for AI not working, that a live bull can take care of.
If all else fails, do try to find a live bull for her.
Because of it being frozen, the semen from the straws moves far more slowly and travels less distance. Therefore it must be placed exactly. Live semen can travel long distances, through a tortuous path.
As one lady put it, "As long as he gets it on her tail, she'll catch". Obviously an exaggeration, but it makes the point.
