I recently installed Flex to use the memory profiler. It works great and I am able to debug my files, however now whenever I visit a web page with flash a flash movie I get this same error:

```auto
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|%2FUsers%2FKevin%2FDocuments%2FFlex%20Builder%203%2F.metadata%2F.plugins%2Fcom.adobe.flash.profiler%2FProfilerAgent.swf?host=localhost&port=9999 cannot load data from localhost:9999.
    at ProfilerAgent()[C:\SVN\branches\3.2.0\modules\profiler3\as\ProfilerAgent.as:127]

```

Note that I don’t even have Flex running when these errors occur, and they occur _every time_ I try to view a Flash movie. I have tried re-installing Flash but the errors continue to come up. Does anyone know how to fix this?
