EMC2 Crash on startup

When I try to launch EMC2 I get an error and the program closes, if anyone knows how to fix it short of reinstalling it would be great.

Error:

I just got done installing the CNC upgrade package on my Sherline 5400 mill, and i am a new Linux user stumbling my way through figuring out how to use it.

Have you run the latency test?
If not you need to check that first and maybe edit the configuration to lower setttings.

Take a look here...
wiki.linuxcnc.org/emcinfo.pl?TroubleShooting

From your report...

RTAPI: ERROR: Unexpected realtime delay on task 1
This Message will only display once per session.
Run the Latency Test and resolve before continuing.

Unexpected realtime delay: check dmesg for details.

I ran the latency test and I am still getting the same error

-Matt

I got EMC2 to load no problem last week before I got the CNC box and stepper motors in hooked it all up and it decided it did not want to behave after i hooked em up. Where do I go to change the config? I do not have the latency test results on this PC but they are saved on the Ubuntu machine as soon as I get on it tomorrow I will post em. Everything I am using is new to me here sorry about all the questions.


-Matt

I used Sherline 4 axis inch sample, and that is the one that's crashing when I try to open it now to test everything.

-Matt

When I try to open the Sherline sample file the whole program quits, I can open the stepper config no problem. I tried to open the .ini with gedit but it wont let me change anything on the file just view it.
