Please let me know what version of TM you're using...
In the meantime, please take a look at the MTASC Help (Bundles »ActionScript » MTASC » MTASC Help), section 1.3: Debugging, just incase there's some obvious thing you're missing (happens to me all thetime : )
The XTrace debugging feature may be removed from the bundle sometimein the future, as you can get pretty much the same results by usingConsole.app. Take a look at this postfor more information about this (and maybe some more insights on yourproblems with XTrace)
