In Flashbuilder 4 , actionscript projects

1. I clicked on Clean under Project and now i cant run the project as I get a file htm not found.  
In the bin-debug it has no files now… Dont tell me this is unstable!!!

I did this because when I made changes to my file I saved all and run it again and it still ran the old file.

1. where do trace commands appear in flashbuilder?
