I changed to thunderbird when Eudora ceased to offer a service. Nor being very Financial when my computer died I've been using hand downs. Now I have a reasonable laptop I've been trying to get thunderbird back but it won't regognise any password. Click on password not working for a new one & nothing happens. It tells me I don't have an account but when I try to open one with my email etc it tells me I can't because it already has an account by that name. Please help.
