Flash builder 4.7 throwing errors for no reason - is there a fix?

Question

Hello,
I am using FB4.7, right now on an AS project. For some reason, FB has started "locking up" on runtime errors. Meaning, if I run a code with an error, then fix the error, FB still reports an issue at that line, even if the line is blank.
In the attached image, you can see that I am getting a 1009 Error on the second reference to a variable that has been declared directly above - obviously a bs error.  I had a chunk of code there before, that did have the error, but I am still getting the Error, can't test, compile, etc.
Very frustrating, no idea what is causing this!!! Thanks for any input!

Looks like its dying on the first line of code in that method. Try checking:
The methods parameters - perhaps compiler doesn't like TextFormat defaulting to null
   Or perhaps you're using that default null param and its biting you but misreporting the line number.
   Seems like I might have had problems in the past with params, but I think it was with assigning null to a callback function param.
      Instead I had it default to an empty class method called NullMethod, or some such.
Other ideas, although these usually apply to compile time errors and not runtime:
Import statements - are you missing one?
Access modifiers - is something trying to call this method that doesn't have access?
Check for syntax errors higher in the file.
