Insert button doesn't work in free version

Great, Thanks!
I reinstalled JCE and was able to use the Insert button!

Friendly feedback: The free feature list is a bit misleading about being able to link to articles. Maybe add "via URLs only". Without diving into the documentation and going off of the feature list "URLs & Articles - Open any article", someone (me included... and I had skimmed the documentation) would expect the URL and Article tabs to be free in the tool.
