I'm guessing that its choking on the Vector declarations in playerglobals. Make sure you are targetting player10. With FlexBuilder 3 I recall that was a bit tricky - first turn on generate HTML wrappers if it iisn't already. But then maybe its something else.
Hope that helps,
It sounds like your IDE is building more than just the HelloWorld example, and that the error is in some other file. Have you searched for a class called "DemoTLF"? If you're in Flex, do a multi-file search. "DemoTLF" doesn't sound like something they'd put in the SWC.
Richards thanks for your reply, I am targeting the flash player 10 and generate HTML wrappers is allrady turn on , can you help me that anything else causing it.

By default it will use the SDK that comes with Flex Builder, you will need to add the new SDK, and select it as your target Flex SDK, if you haven't already. That will ensure that it is using the correct version of the compiler when it builds. I don't remember exactly how this is done, but I think if you select "Preferences" there will be an option, perhaps under "ActionScript" for installing the Flex SDK. I would suggest checking to make sure this is done.
Robin , for ur help
I got this , I was pointing the flex sdk which is else in my hard disk
rather then Flex/builder/sdks
What i did i just copy the latesst sdk into Flexbuilder/sdks and this
