Demo errors - cannot see a single file

First of all please take my apologies if I am not posting in right category. I have been asked to report bug on here but didn't get any more specific instructions.

Demo isn't working for me. I wanted to test ownCloud, but any file I click on it throws an error. Different errors for different file types.
Below you have screen shots of what happens when you open JPG, MP3, PDF (screenshots in that order)

So I had 3 screenshots here, but I am only just registered TO POST THIS and I am not allowed to post more than 1. Silly.

I discovered it yesterday at 15:00 GMT and this is still a problem. Please let me know if you need any more information.

good catch i will report this to sysadmins
