Trying the new gpu plotter....

my config...
gpuPlotGenerator generate 0 0 plots 4163282010088137402 15662000 20480 500 64 128
PAUSE
The error I get says "[-54] Error in step1 kernel launch" It does this
after "Setting OpenCL step3 kernel static arguments"
Any ideas? Is my config bad, I started with pretty low numbers. I should also mention I'm plotting on my cpu right now with 4 cores (i2720qm), and have 2/8 gb free.
