I installed Ubuntu for the first time yesterday by running Wubi on Windows Vista Home Premium. For all of yesterday and up to lunchtime today Ubuntu was working fine. I followed the instructions on a forum post to remove Evolution Mail via the synaptic applications menu. I proceeded to log out of Ubuntu and reboot (I hoestly can't remember what for) Anyway, ever since I have not been able to log in to Ubuntu. I enter my username and password as normal and they are accepted, however moments the log in page displays again. This continues in an endless loop.

The password is definitely correct because I get an authentication error if I enter anything else. I know I am not the only person experiencing this issue. None of the suggestions I have found by searching this forum have worked.

Someone must be able to fix this problem, please offer any advice you can.

Thanks a lot!
