3ds Max :: Using 2011 Graphite Freeform Polydraw Tools To Retopologize A Scanned High Poly Model?

I'm trying to use 3dsmax 2011 graphite freeform polydraw tools to retopologize a scanned high poly model.

Here are the steps I went through:

1-Imported the high poly mesh (.obj)
2-Converted to editable poly
3-Used ProOptimizer modifier to make the model "lighter" for my pc
4-In the polydraw tools, I selected "Draw On: Surface"
5-"picked" the high poly model
6-Selected offset 0,2
7-Created new object using the polydraw tools "New Object"
8-Froze the high poly model
9-Started retopologizing

The problem is that during the retopology process, my mesh doesn't ''stick'' to the reference high poly model... so I have to stop every now and then to adjust it which takes a lot of time.

I do know that there are a lot more specialized retopo tools like Topogun and 3Dcoat, but acquiring a new tool is not an option at the moment.
