Problem with Flex Builder

I have created on sample mxml application. While running the application, getting error:

File Not found: in bin-debug folder the mxml is not compiled to html.

Suppose i have created file name: newFlexTraining.mxml.when i run this mxml, getting error, newFlexTraining.html is not available in bin- debug.I checked in bin-debug folder 开发者_StackOverflow中文版in flerx builder, the html file is not created. Earlier it was working fine.But now i am getting this problem. Can you any one pls explain me ASAP.

Thanks, Ravi

Did you modify html-template?

Delete everything from bin-debug folder, clean the project and rebuild it.

in bin-debug folder the mxml is not compiled to html is this the original message? Post the original error message.
