I really cant thank you enough for your help.... Really is appreciated!
You're welcome glad we could help
I stopped using this as my email client about a year ago, can I just go to C:\Documents and Settings\Andy Vickery\Application Data and delete the Thunderbird folder?
Yes that would do it or i can give you a fix that will do it for you if you wish.
Let me know in you're next reply and if you have any other questions.
