Problem with link for file renaming

Dear

I did a paper and published the following link:

http://prezi.com/nay7a040swub/present...

But then I changed the file decryption in PREZI and the link no longer works, and I can no longer change the link now in the place where I published.

The correct link where you see the paper is as follows:

http://prezi.com/nay7a040swub/present...

Consultation. Since I can not? Edit the link I posted and it is incorrect or mme leads to the presentation, I can make a copy and link the first link?

Thanks in advance
