Invalid class string - end note x2 - vista - office 2003

I am getting this error message all the time when ever i try to insert citation. It was working fine previously. I did not work with endnote for a while and i started working again. First i didnot get the tool bar, then i thought it needed update so i updated it… from then i am gettting some or the other error message. when i go to end note it says member not found. Can some body help regarding this…

Hello Loga,

You may find the information at http://endnote.com/support/faqs/CWYW/faq13.asp helpful.

If that doesn’t work, you may need to disable User Account Control in Vista, then repeat the listed steps.  Take a look at http://www.petri.co.il/disable_uac_in_windows_vista.htm for more information on how to do that.

I am still getting the same message, I tried reinstalling the endnote but still having the same problem. I tried all the steps mentioned by you. But one thing I found is I have endnote x tool bar and not endnote x2 tool bar in word. Is that a problem, if so where can i find x2 tool bar. I do not know whether x2 tool bar exists but I see there is a difference in the tool bar which I already had but now after updating and reinstalling my tool bar looks different and says invalid class sting…please help. I have tons of articles saved and need to write and complete my project…asap…kindly help…thanks a lot…I appreciate your time and support
