Flash Builder 4.5.1 Error when trying to run

[stottsjr]

Hi,

Since I installed 4.5.1 of Flash Builder (OS/X 10.6.7) I get the following error when I try to run anything:

An internal error occurred during: "Launching New_configuration".

java.lang.NullPointerException

I created a new project to make sure it wasn't any bad code causing the issue, but it still has the same error with just a blank project.

Any thoughts on what might be causing this?

Thanks!

Can you please post the contents of workspacedir/.metadata/.log?

Are you on the same workspace as 4.5? Can you try with a new workspace?

Not sure why, but when I did a "Run as" once and now the "Run" button works fine, it works in completely new projects as well.
