AH YES!!! LE SACRE!!! (I just LOVE that piece!) Which orchestra is it?
The links should work fine, I myself have downloaded the pdf's, perhaps it's worth another shot. If one has canceled the file download when it was not completed, then it would be damaged. I have experienced problems downloading things at one point of time when I was notified the file was finished downloading. The weird part was when the file size was smaller than the file size on the site, but then I tried it anyways and the file was "damaged". So, one way to ensure a non-damaged file is to make sure that the file size matches the one stated on the website.
