I'm having trouble using Flash Builder 4. I first tried to use it as a plugin for eclipse, which didn't work, as I got an error when trying to open .mxml files. The error is the same one discussed in another discussion: a null pointer exception. I tried to follow the solution to the discussion but couldn't figure it out. So after uninstalling and reinstalling Flash Builder in plugin form, I downloaded and installed it as a standalone. The installing worked fine but when i tried to open the application, all I got was the license agreement popup repeatedly, even after I pressed accept. I'm not sure what's going on, but I've been told that it's a licensing problem. Is there a quick fix for this?
Can someone please help me? I doubt that I'm the only one who has seen this problem before.
