This is what the error screen says Any help will be greatly appreciated

I followedthe instructions posted here: wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.4

This might indicate a bad or incorrect .bit file. Can you tell me the bitfile name, length and date?

Peter ,there are 6 different .bit files in the folder /lib/firmware/hm2/5i23
How do I know which has been selected, I have selected from sample configurations_hm2-servo_5i23

Thanks John as you can tell I'm at the foot of the learning curve!
This is the line from 5i23.ini CONFIG="firmware=hm2/5i23/SVST8_4.BIT num_encoders=3 num_pwmgens=3 num_stepgens=0"
Properties for SVST8_4.BIT: 207.5KB (212462 bytes)
Modified mon 03 may 2010

Can you email me that bitfile, I'll test it here
(cant think of an easier way to get that file by itself)

bitfile sent thanks for the help

good news, just updated to 2.4.2 and 5i23 7.1 and all is well
