Flash CS5.5: Application Descriptor File Cannot Be Parsed

I am working with an iPad application with Adobe CS5.5 for few days now.
When testing the application, I started getting an error as shown in the screenshot below.
I deleted the descriptor XML file, but Adobe is still sending the same exact error.
How can I troubleshoot the error?
I don't know what it is that is not being parsed. Help please.

Adobe Flash CS5
Application descriptor file cannot be parsed
OK
