Lately, when I open a MS Word 2000 doc on my PC, it will freeze and later a message will appear saying "NOT RESPONDING". Everytime this happens I can see the Zotero toolbar in an odd position, centered at the top, and since I have recently installed it, I fairly certain that was causing MS Word to freeze. However, to erase all doubts I've tried reinstalling, repairing, and un-installing then re-installing MS WORD again from the original CD but the Zotero toolbar is still visible despite having restored WORD to default. Is there any alternative way to uninstall the MS-Word Plug-in from my PC.

P.S. My PC also came with a MS WORD 2007 demo and when I tried to see if that worked in it's trial/basic mode, a message appeared that said "unable to open Zotero".... Hence my reasoning that somehow the plug-in is over-riding MS Word 2000 and 2007 even when restored to default setting.
