I'm trying to edit the source files Adobe Flash Builder 4
And when I finish edit and want to keep it shows me the following problem:
See details for more information.
Encountered errors or warnings while building project VideoChat.mxml.
unable to open 'locale / es_ES'

What should I do?
I tried to look for people with a problem like mine, I found a solution but was not understood
Write me put this command:
-locale = en_US-source-path = locale / {locale}
But I do not know where to put it
I will be happy to help staff forum
Thanks in advance
