So my trusty ShopBot computer bit the dust today. 13 years is a good run, right? (motherboard won't post...)

Anyway, I get a replacement machine up with Windows 7x64 and after a lot of scrambling I get the machine to recognize my IUSB24AT RS-485 interface board - it's basically a USB to RS-485 box. It appears as COM5.

When I ran the SBP software, I tried to pick COM5 for the VFD via the RPM tool's configuration screen. It refused to accept "5" for the port # - it never threw a dialog but, it never dismissed the configuration window on "OK" either.

I cancelled out of it and the RPM tool went away. Now, nothing I do will bring up the RPM Tool! I can see the window flash on to the screen for a fraction of a second before it vanishes again.

I'm using SBP v 3.8.50

I NEED my RPM control. Help!

Thanks!
