Loss of contents

Well, I updated from an earlier version to 2.5 last night and found that almost half of my images, vids and articles have been gone. I seem to fail to retrieve them.

And the imageshack-uploader isn’t working any more. It doesn’t even show up in the nav bar like it did before. (I don’t want to store all those images on my server so ImageShack is perfect to store half of the images there)
And the wp-vidavee tool,which worked just perfect for me, is also no more accessible. I don’t like the video / Media Library tool that comes with 2.5. Sorry
Not very happy about that.

But in general the new look of the dashboard etc is cool.
