Flash Builder 4 Beta 2 throwing security error on every run

Question

I just installed the beta 2 version of flash builder, but every time I try to actually run anything built on the 4.0 SDK, it throws a security runtime error when trying to access the 4.0 sdk swf.
SecurityError: Error #2148: SWF file ......../Test.swf cannot access local resource ....../Test/bin-debug/framework_4.0.0.10485.swf. Only local-with-filesystem and trusted local SWF files may access local resources.

I'm running eclipse galileo (carbon) on OS X. If I create a 3.4 project, everything is fine.
Any ideas?

Hi Mike,
It seems that part of my problem is due to an error in .actionScriptProperties (which file doesn't show up in the package explorer): the "mainApplicationPath" refers to a non existent file "StockQuotesExample.mxml" (see screen copy below):
So I manually modified the property to replace it with the correct file name:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<actionScriptProperties mainApplicationPath="StockQuoteExampleWebService.mxml" projectUUID="2376e773-57bd-4f6a-9034-7911cb1df6d8" version="6">
  <compiler additionalCompilerArguments="-locale fr_FR" autoRSLOrdering="true" copyDependentFiles="true" generateAccessible="false" htmlExpressInstall="true" htmlGenerate="true" htmlHistoryManagement="true" htmlPlayerVersionCheck="true" includeNetmonSwc="false" outputFolderPath="bin-debug" sourceFolderPath="src" strict="true" targetPlayerVersion="0.0.0" useApolloConfig="false" useDebugRSLSwfs="true" verifyDigests="true" warn="true">

    <libraryPath defaultLinkType="0">

        </modifiedEntries>
        <excludedEntries>
          <libraryPathEntry kind="3" linkType="1" path="${PROJECT_FRAMEWORKS}/libs/flex.swc" useDefaultLinkType="false"/>
        </excludedEntries>
      </libraryPathEntry>
      <libraryPathEntry kind="1" linkType="1" path="libs"/>
      <libraryPathEntry kind="3" linkType="1" path="G:/Program Files/Adobe/Mate/libs/Mate_07_8.swc" useDefaultLinkType="false"/>
    </libraryPath>
    <sourceAttachmentPath/>
  </compiler>
  <applications/>
  <modules/>
  <buildCSSFiles/>
</actionScriptProperties>
Unfortunately, I still get the same error message in the Flex Compiler settings page, in the project's Properties. Indeed, the message looks for the file in the wrong path: "G:\Program Files\Adobe\Mate\src\src", when it's really in "G:\Program Files\Adobe\Mate\src"... The screen shot below shows my directory structure:
This is an example application that I downloaded to test the Mate framework; maybe it set it up wrong. Also, I created an SWC file with their new made-for-Flex 4 library, but that didn't solve my problem.
Thanks for your help,
Chris.
