@mogulskier9† I just released version 1.8.2 to address the "Undefined property: CoolCarousel::$icon" issue. I apologize for not finding that DMS 2 change prior to the release of DMS 2; however, it would not have affected output/display/performance on the front-end. I appreciate you reporting that issue so I could fix it for all users.
Regarding your "Warning: Cannot modify header information - headers already sent" issue, this is the first mention of this that I have heard of, and I have never experienced it myself. I'd suggest updating to v1.8.2 and see if this fresh download of the plugin clears up your issue. If not, you'll need to start a new topic in my support forum ( http://forum.pagelin...cts-by-cliff-p/ ).
Regarding dissatisfaction / refund requests, that's all handled by PL staff so you'd need to email firstname.lastname@example.org with your request if you choose to pursue that issue. I believe the guidelines are purchased within the last 30 days and only if it's not working, but it's 100% a PL decision. I'm not informed of how they make their refund decisions.
Best to you,
