Error Scheduling in SSIS even after configuring the configuration file

I am having very difficult time trying to schedule a package in SSIS through Management Studio. I am using SQL Server 2008 R2. My package runs fine when executed directly from BIDS. However when I create the job and run it from Management Studio it throws various errors. When i put DontSaveSensitive the package does not run from BIDS but when I put as EmcryptSensitivedataWithKey it runs on BIDS but fails in Management Studio with error DTS:Password with error

0x8009000B Key not valid for use in specified state. You may not be authorized to access this information. This error occurs when there is a cryptographic error.

I have changed the package setting to DontSaveSensitive and modified configuration file to include password in connection string.

My XML looks like this:
