Error importing File in Blackberry Desktop Software

Question

I have developed an application for Blackberry and am trying to import the cod file into my device using BlackBerry Desktop Manager. I try to import the .COD file. The application was installed earlier on this BlackBerry. When I try to use the Import option I get the error message saying -

"There was an error importing files. No additional applications can be found. Your file might contain applications that already exist in the application list, are not compatible for your device, or have errors."

Answer 1

I changed the Version filed in BlackBerry_App_Descriptor.xml and then signed the deploy-able. Don't get the message any more.
