Flex Viewer 3.0 loads a blank screen

Question

I downloaded the source for Flex Viewer 3.0 and compiled it without making any changes to the code.  It loads a blank page when I hit the URL.  The progress bar flashes briefly, then blank page.  I'm using the source because I have a few minor changes to make that only affect icon sizes and such.  But right now no changes have been made.

I found only one post related to this issue.  The OP discovered that he needed to be using SDK 4.6 and then had no further problems.  I am using Flash Builder 4.6 Premium with SDK 4.6 and the .swc that comes with the Flex Viewer 3.0 source code.

What is causing this?

Sorry Robert that's my fault for typing in a hurry.  As you said, the SDK didn't come with the source download, I downloaded it seperately and pathed to it in Flash Builder.  Sorry I mispoke there.

I figured out the problem.  After importing the project initially there were 80 errors reported in the 'Problems' pane.  I was expecting those errors to clear after pathing to the SDK but they didn't.  Then I renamed the project and that seemed to trigger a reload and all the errors were cleared.  Then I exported the release build and it worked.

Curt,

In the future ensure you post Flex Viewer questions to the flex viewer forum.

This part of your post concerns me:and the .swc that comes with the Flex Viewer 3.0 source code

as the Flex Viewer source does not come with the Flex API swc any more the lib folder only contains a text file that explains how to download the Flex API swc to use in your project.
