Drivers for Refine & Pcut loaded on same computer?

[firemalt 10]

So I got my refine in yesterday. After I downloaded the USB to serial converter driver, I set it to COM1 as I did with the driver for my Pcut.

When I plugged the refine into my comp, it made SBE run super slowwwww.

Just curious if anyone else is running two different cutters via USB cables, and how you have things setup to where the two drivers aren't fighting against each other?

Thanks for any help or suggestions. Worst case, I'll just disable the pcut driver, cause I think I'm going to use the refine as my main cutter!!!
