I think I found the problem. (It’s to do with unicode byte order characters before the header comment.) It should be fixed now.
Can you give it another try, and contact support if you’re still seeing a problem?
Thanks, and sorry for the hassle.
Oh, and crozer: You should still open a ticket even if you think it’s just you having the problem! We’ll try to help anyway, and it may well turn out to be not just you after all. Having tickets for problems helps us figure out if it’s a one-off, or if lots of people are seeing it.
