CKEditor does not load anymore, no idea why

Hey everybody

Since some days CKEditor doesnt load anymore on my website:

http://emuesch.ch/pages/12/edit

I dont have any idea why, because I didnt change anything for a long time, and sadly I am on a journy and not at my own PC so my possibilities to examine and fix this are very limited.

Could somebody please help fixing this? I guess it is a very easy to fix problem, but yeah, I am basically stuck with only an IE and no developer tools here...

Thanks a lot
Josh
