Hi all i have been looking around for ways to resolve this error and everything that was recommended has not done anything.

**What i am trying to do:**  
I am trying to access external swf’s from one webserver to another. I am using the amazon cloud to store all my media and i am then using a seperate erver to store my main swf.

**What i get**  
All i keep receiving is the #error 2121 security sandbox error even though i have done what i have been through searches on google.

**What i have:**  
I have a crossdomain.xml that has allowed other none swf files to load from a different webserver but when i try to load swf files from a different server i have no joy at all and it just fails with the 2121 security sandbox error.

any help much apprechiated  
Regards  
Mark
