Crashed

It worked amazingly for a few weeks... then it stopped. I travel to 9 schools in my district and I did a great lesson with this app at two schools with appointments to do more, but it will not load. Tried iPhones 4, 5, & 6. Tried dozens of iPads. Tried with and without schools filtered internet. Deleted and reinstalled. Tried standing on my head. Tried to e-mail, tweet, FB message and call. No change.
I know its a free app and theres less right to complain, but it breaks my heart a little. One hard-to-impress, veteran science teacher said it was the most exciting chemistry lesson hes been a part of. I hope it can return soon. David Dyer.
