Error adding XmlSyntaxLanguage to Form

I just recently purchased a license for the web languages add-on and am receiving an exception when I try to run my application after I added it to my form.

The line I am receiving the exception on is in the InitializeComponent method:

this.xmlSyntaxLanguage1 = new ActiproSoftware.SyntaxEditor.Addons.Xml.XmlSyntaxLanguage(this.components);

 Here is the exception info:

System.InvalidCastException was unhandled
  Message=Specified cast is not valid.

 I had version .300 installed previously, tried un-installing and re-installing v. 302, but the error remains.

I created a .licx file and added it to my project, but it did not help.

Can someone shed any light on this problem?
