Lauch failed (initial content not found)

Question

Hi all,
I've run in to a nasty error:
I have an MXML file which indicates an error next to it's filename (the little x in the red box). However, when I open it Flash builder does not indicate an error on any of it's lines. Removing newly written content and saving did not help.
After a while trying 'stuff' I tried the "Clean..." option from the project menu. If I do so, Flash builder no longer shows the error until I try to run or debug the app. However... Flash Builder fails to start the app at all now .
It first states the project contains errors and If I opt to proceed building Flash Builder now gives the error:
"Launch Failed"
"Process terminated unexpectedly
Initial content not found
Launch command details {some details on which files etc.}"
It renders the project useless since I cannot test anything. Anyone any bright ideas?
Kind regards,
Manno

Hi Anirudh,
Thanks for the tips.
I should have posted but i already figuredit out. There was à conflict with an existing flash class even though in the offending line full path to the class was defined. Most annoying was that there was no indication in the gutter.  I'll see if i can reproduce it in a barebones file to post it here.
Kind regards
Manno
