Torque's Profiler?

I'm trying to use torque's profiler but I'm getting an exception as soon as I start profiling (by pressing F2):

System.Collections.Generic.KeyNotFoundException was unhandled
The given key was not present in the dictionary.

Anyone else having this problem? I've never touched the profiler before. This is the first time I've tried to use it.


EDIT:

I jimmy rigged it by changing:

Profiler.cs (TorqueCoreutil)

if (!isRoot)
                        thisBlockInstance = _currentBlockInstance._childHash[thisBlock.Name] as ProfilerCodeBlockInstance;
                    else
                        thisBlockInstance = _rootBlockInstanceHash[thisBlock.Name] as ProfilerCodeBlockInstance;

to

// get the existing block instance
                    if(!isRoot) {
                        if(_currentBlockInstance._childHash.Count > 0)
                            try {
                                thisBlockInstance = _currentBlockInstance._childHash[thisBlock.Name] as ProfilerCodeBlockInstance;
                            } catch { }
                    } else {
                        thisBlockInstance = _rootBlockInstanceHash[thisBlock.Name] as ProfilerCodeBlockInstance;
                    }

thisBlockInstance = _currentBlockInstance._childHash[thisBlock.Name] as ProfilerCodeBlockInstance; was the line that was throwing the exception


Now, as soon as I turn on the profiler the speed of the game goes aaaall to hell. Is this normal?


EDIT:

Turns out it's slow because it's spamming silent exceptions like craazy. Turns out my jimmy rigging came to no avail.

Any thoughts?
