i get this error:

Click on the photo to make it bigger

Any ideas? i downloaded the file called sswc.rar from megaupload extracted it and lauched.. then i get the error.
is it the wrong client or something? is there another place i can download the entire client in one piece?
I havent replaced the media.pk2 if that matters, its not updated either i think the file was uploaded in the end of june.. do i need an newer client?
