AudioRestore plug-in help required

I would like some insight as to what the various components in this plug-in are all about, and how they will affect the sound. There is no help menu that appears when I press F1, and I cannot locate any specific information in the general help menu.
Using the default settings, seems to result in too much sound loss as the "cleaned" version is quite muted compared to the original recording. I'm recording vinyl records using the Audio Technica AT-LP2D-USB Turntable.
 
Thanks in advance to any/all helpers!

I could use some help with this also.  Basically I need to understand how to "de-click" my audio files for recording to CD.  I've tried moving the slider in the "declicker" area, but that only seems to lower the tone of the click, but it doesn't get rid of it nor make it any quieter.
