i don't find any link that can update flex-builder 3.2 and i am using updated sdk still i need updated plugin for Flex builder 3.2??

Errors like this are commonly caused by a version mismatch. Are you using a components in external SWCs or other projects? Make sure that those SWCs/proejcts are compiled against the same SDK version as your main project.

I do not believe that the Flex Builder Plugin was updated for every update to the Flex SDK. But, Flex Builder should work with any version of the Flex SDK.
