EndNote X1 - word 2007 startup issue

Hi All,

Thank you very much for any help that may be provided. I have an error coming up when I open my word 2007 now.

I installed EndNote X1 on my vista business machine running word 2007 and I had nothing but issues so I went into programs and uninstalled but evidently not everything uninstalled.

I get this pop up error

ENDNOTE X1

Invalid Class String

Any time I open word. I just want it to be removed as I have had nothing but issues.

Any help greatly appreciated.

Thanks
