Wordpress Version 2.5

I have upgrade my another blog and now using the Wordpress 2.5. Man, it is really not easy dealing with the new one as yesterday when I upgrade it, my Mushie Moshiu was down for at least half an hour due to some missing files. Then today, I started to post and guess what, I could not find some of the button and it's a bit confusing when I want to upload the torrent files. I can't seem to find the upload button, the publish button and even when I wanted to update the widget, I spent more than 10 minutes just to make sure I did not press any wrong button that might delete or change the setting..

Guess it is not easy, for all user of Wordpress that are planning to upgrade, think twice before doing it.
