All yeast are quite similar, really. It's surprising how different instructions manufacturers print for basically the same organism.

From my experience, it is best to start with 30 C30°C water. Then let it cool to about 2020° before adding to wort. Unless I have an opportunity to actually speak with the one who wrote instructions, I simply ignore them if they tell me to go warmer. So far, so good.

Even if for particular strain higher temperature is OK, don't just throw 40°C yeast to 19°C must. Let them cool. Imagine how you feel when you jump from hot sunny beach into a cold water. Not good, right? For yeast safe temperature difference is about 5°C, as far as I know. But I would try to get even closer if feasible.

If you are worried about current batch, try rehydrating second package in lower temperature and adding it. If you are sure your conditions was sterile, you may want to wait up to three days. They still may kick in. Also, was your wort properly aerated? If not, this is the last moment to do it.
