Application Update error 907

[ Edited ]

Hi All,


         I have a small problem. i had developed an application for blackberry which is released in market. Now I had to make changes to the application so that new version can be released. When I tried to sign and update the application over existing previous version application on device i get the error "This application is not compatible with your device" in desktop manager  and Error 907 Invalid COD in OTA. Can any one suggest me what might be probable reasons for getting this error. I want application to get updated on the previous version.  If i delete the old version of the application and install freshly Application loads perfectly fine.
