I had the same issue with Templates Not being available at all,. I was using FireFox and the template button was nowhere to be found. Quite frustrating and wasted time. I then thought to try it in Chrome and lo and behold, the Template button was there in all it's glory. The Template Library showed up as well. So, if you're using Firefox then that is likely the issue (not sure why Evernote doesn't like Firefox) but you need to use Chrome,.. I hope this helps.
