BlurXTerminator for aberration correction seems to make things worse

I'm following along with the NGC 1491 workflow and the step where using BTX to correct aberration doesn't give me the same result when using version 2.0.0. I've attached screen shot with the first being the "corrected" version and the image to the right being the original. Am I using it correctly? It looks like it's being sharpened but not corrected. The result is these "extra stars" that get generated on the left-hand side.

    No, you are not using it correctly.
    You must select the new AI version. AI 4. 
    Press the "Select AI" and choose between the two files..that one that has a "4". You can see in your screen capture you are using AI2. You are demonstrating precisely the improvements that AI4 has.

    OK, I solved the issue. It seems that I have to select "AI version 4" which I didn't see. After doing so the stars are now corrected as expected.
