I purchased and successfully installed HTML5 MP3 player. It appeared in Dreamweaver 21.0 in menu under Window > DMX Zone. I then purchased and installed your HTML5 Video Player. Now, In Dreamweaver, under Window > DMX Zone, only HTML5 Video Player appears, and HTML5 MP3 Player option is gone. I double checked my DMX Extension Manager and both plug-ins are installed. I also re-installed them with Dreamweaver closed, restarted Dreamweaver, but still only the HTML5 Video Player is available as an option. What happened to the MP3 Player? As a workaround, I can copy and paste the code from another web page, but that is obviously messy and difficult.

In DMX Extension Manager, both plug-ins are shown with a red gear icon and a red triangle on the left side of each plug-in's box. Is that good? What does that mean?

Thanks for your prompt attention to this!

Hello John,
Both of the extensions should be available in the DMXzone Panel (which you activate through the Window menu).
If there are issues, please try reinstalling them in DMXzone Extensions Manager.

Well, I opened the Extensions Manager, de-installed both extensions, and then restarted the computer. I then re-opened Extensions Manager and first re-installed the MP3 Player, then re-installed the Video Player. Opened Dreamweaver, and the DMX Zone Panel under the Window menu only showed the MP3 Player, but not the Video player, tho both are installed according to the DMXzone Extensions Manager. Any ideas?
