are you launching it from a netwokred pc or somthing. In some instances, Other programs wont allow you to pin them to the taskbar if you are networking them

After I tried everything else, which did not work, I uninstalled then re-installed the application. Now I can pin SED to the task bar. Not sure why I had to do that, but, it works now so I'm not gonna argue with it. Thanks for your time & assistance.

I saw this after I posted my last message. I was able to resolve the issue. I didn't have it networked. Thanks for your response though.
