Hi folks,
I'm a hobby CNC enthusiast, working for a couple of years now with a self built CNC machine. My setup includes an old pc using a PCI card to connect via a parallel port to a 3axis tb6560 controller. my spindle is the 2.2KW with the HY VFD.
This setup worked perfectly until it didn't. For some reason every time I tried to open gmail the computer crashed completely (lost power all together). I decided to replace the USB stick holding the Linux installation with a new (and bigger) one.
I have successfully (I think) installed the rtai kernel and linuxcnc, the old issue was resolved, my latency test looks great and I can control the motors while in the Stepconf Wizard.
The Problem is after I finish setting the configuration and trying to open the launch icon, first I get a message that it is not .exe. when I hit launch anyway is shows the linuxcnc logo as aspects and then crashes with the attached report.

I would appreciate any help on the subject, I already wasted crazy amouny of time trying to get my setup running.
Thanks.
