Error Message Running A SSIS Package In A Job

Hello,

I'm having problems when I try to run a package from a job in SQL Server Agent. I have the same package in a server and it works fine,but when I try to install it in a different server I keep getting this error:

I can run it from Integration services Server, from BI, and I tried modifying the ProtectionLevel property to DontSaveSensitive and ServerStorage. I have other packages that run in jobs, and they work fine...but i don´t know what else to do....By the way, I'm using an administrator user to run the package.

Please help! =(
