Hello,
I was able to use your custom ribbon tab XML just fine.  The only thing is, the copy you provided had a bunch of illegal characters embedded in it (like reverse quotes?), I'm not sure if they're showing up in your version of the XML or not.  Anyway,
after replacing those with straight quotes and fixing some other misc formatting, it worked fine.  I created an empty SharePoint project and added an empty element, then added your XML to the Element.xml file.  In SP, I created a new custom
list and the "My Tab Name" tab appeared with a button that displayed "Hello World" when I clicked it. So, I recommend checking the formatting of your XML.  Just look for red squiggles in the editor and fix them.
