Unfortunately our security settings wont allow external links on the wallet server, I will keep trying to sync the normal way.
It seems that the problem is external link to blockchain backup. I think there is a solution, but I don't know how to do it. There is a coin that has this same problem (truckcoin)
https://bitcointalk.org/index.php?topic=716182.0. The DEV solved the problem using a file bootstrap.dat (blockchain bootstrap). I don't know if it would work and if the exchanges agree to such a procedure.
