To touch on something you asked earlier...I'm not 100% on this so maybe a true expert can confirm, but I don't think it is ever a good idea to put yeast in the freezer. Refrigerator, yes. Most strains of yeast will go dormant at refrigerator temps and keep for approximately 7 months, though as said earlier in the thread, the viability drops significantly.
In the future, if you are unsure about the viability of your yeast(or anytime for that matter) I would make a yeast starter to proof them and to get their metabolic rate up before pitching. There are many great threads on here about how to make a starter. It is really simple and takes the uncertainty out of pitching. Again, I second the idea of having a couple of dry yeast packs squirreled away in the fridge. That way if you make a starter and the yeast fails you have a backup plan!
