Try this one. That worked for me. I have Eclipse Galileo (3.5) and FlexBuilder 3.0
Goto your Eclipse Installation (example my installation is C:\eclipse) and there to this folder: C:\eclipse\links
Open File or create "com.adobe.flexbuilder.feature.core.link" and type in this text: path=C:/Program Files/Adobe/Flex Builder 3 Plug-in
In my case the word path was missing. After that restart your Galileo and it should work.
