Thanks for your honest (albeit brutal!) feedback. I'm sorry that the EasyRotator for WordPress plugin hasn't worked out for you yet, but we're committed to making every effort to help you get up and running.
First, it's important to distinguish between the requirements for <b>creating/editing</b> rotators and <b>viewing</b> rotators. As mentioned under "Requirements" on the plugin homepage on the repository:
To edit rotators, Windows or Mac is required. Linux usually works, but is not officially supported.
That <b>linked article</b> provides directions for getting up and running on Linux. Please try those instructions and post back if you run into any trouble.
The other side of the coin is <b>viewing</b> rotators. All modern browsers and platforms (including Mac, Windows, Linux, iOS, Android, BlackBerry and other mobile devices) are fully supported. If you're having trouble with a specific rotator, please post the URL and we'll look into the issue.
Finally, just to clarify -- the version of the plugin listed on the repository is the Standard, 100% free version. There are optional features available in the editor which require the purchase of a Pro license, but those enhancements are purely optional and <i>extend</i> the standard functionality. I couldn't find any record of a purchase under your company name; if you have purchased an optional Pro license under an alternate address, please get in contact with our quick and responsive support staff to work out the issue. In keeping with our 100% satisfaction guarantee, we'll happily provide a full refund if the trouble can't be resolved quickly and to your full satisfaction.
Thanks again for your feedback, and I look forward to hearing back so we can help you get up and running.
