Flexbuilder 3 export release build click throws NullPointerException

Question

Hello!
Please help me build a release version of my app.
When I click the "Export Release Build" button, nothing happens.
From the Eclipse application log, I see that ExportReleaseVersionProjectAndLocationPage.getDefaultOutputFolderPath throws a NullPointerException.
Some things I've tried:
Search extensively on net and within adobe forums...
I tried to guess at the default output folder location -- creating an bin-release folder...
Reinstall the whole stack on both OS X and a Windows XP... nothing.
My primary setup:
J2EE/Flex/Postgresql app, deploying to tomcat 6. Using flex builder 3 plugin for eclipse 3.4 with flex sdk 3.5 (though I tried with 3.2 as well). Running all this on a mac book pro. App has grown such that the low-powered clients (in a health clinic in rural uganda) can't handle the debug version very well. Just trying to make things a bit faster... Help!
Thank you,
kuang

Sounds like this bug http://bugs.adobe.com/jira/browse/FB-22946.
You might want to try closing projects that are unrelated to the project you are exporting.
