Hi, I love this plug-in, but haven't been able to get it up and running. I think it may be my htaccess file, but when I go to Bluehost and do a search, it appears I have eight different htaccess files. Some of them have the word "old" in them.
In any event, I have limited behind the curtain computer skills and I'm not really sure what I'm doing. I would add the lines your readme.txt suggests, if only I knew where to add them. Still, I'm uncertain if this is actually the problem.
I'm using a theme called "Alyeska" that I purchased at Theme Forest, if that's of any help. All of my other plug-ins work just fine.
