[Evolution] Cannot choose server types, calendar doesn't work anymore

[Mezziah gmx net]

Hello.

I'm using Ubuntu Linux 6.10 and it seems that I wrecked the whole Evolution program.

First my problem was only the calendar. It kept saying that it can't find a calender source, although I 
didn't change anything regarding Evolution.
Then I tried reinstalling Evolution several times, but it didn't solve the problem. apt-get remove evolution 
--purge also wasn't helpful.

So I removed everything by hand what I could find and also removed some settings using the gconf editor.

Now I only can choose Exchange as the "incoming server" for my mail account, POP, IMAP and so on are suddenly 
gone, for both directions (incoming and outgoing server). The calendar app keeps telling me that there isn't 
a calendar when hitting the "new" button.

It's a bit hard to describe, though I hope that you understood me. 

Thanks in advance for your help.
