My trial limit was reached, supposedly

I decided to pick up the site yesterday because I heard that this was a good site for smut. I generated a chapter or three for one story, then made another one. The first story was made earlier today, but before the credits were reset, so the credits I have should be at 100 prior to use. And it was, then I generated stuff, and now it won't let me anymore despite having 64 credits left. I don't know what happened and I don't quite understand what it means by my trial limit.
