Hi Kathy
Are you interested in trying again to store them? I use the saran wrap method and it works great. I can look for a link of instructions if you want.
I start my dahlias in pots because I have experienced rotting starting them in the ground and having a very wet spring. I can control the moisture better in pots. But, I in my experience they do not bloom any earlier starting them im pots. I don't think getting tubers in May is too late.
