TechSmith may want some clarification on this. For example, you mention using version 13. But did you just install 13 from an earlier version and you dislike the version 13 UI? Or are you saying you WERE using version 13 and you moved from there to the newest 2018 version?
Whichever scenario it is, can you more clearly articulate what you mean when you say: It went from intuitive to down right frustrating.
