Autostarting the application in Blackberry

Hi All,

I got the Blackberry JDE Controlled API Registration key for automatically stating our application in the Blackberry. (In the reference doc it is mentioned that for auto starting the application we need signed binaries.)

Our application ".cod" files are signed with the installed keys. In the project properties "Auto Run on Startup" is also selected. But the application is not starting up automatically.
In the blackberry emulator it is working fine.

Any guidelines on this are highly appreciated.

Thanks in advance
