RemoveDirt

[thunderclap]

I'm new to the world of AviSynth scripting and need some help. I've been trying to get Pinterf's RemoveDirt working for about a week with no luck. I have the latest versions of AviSynth+ and AvsPmod installed as well as the x64 version of RemoveDirt. The script seems right since AvsPmod doesn't through up any errors, however when I export the clip it doesn't seem to have removed any dust or hair or anything. The script I'm using came from the RemoveDirt site:

function RemoveDirt(clip input, bool "_grey", int "repmode") 
{
    _grey=default(_grey, false)
	repmode=default(repmode, 16)
	clmode=17
	clensed=Clense(input, grey=_grey, cache=4)
	sbegin = ForwardClense(input, grey=_grey, cache=-1)
	send = BackwardClense(input, grey=_grey, cache=-1)
	alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode ) 
	restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
	corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
	return RemoveGrain(corrected, mode=clmode, modeU = _grey ? -1 : clmode )
}

Any idea what I'm doing wrong? Any suggestions?
