Update to 2,9 and Hal Configuration don't Pop-Up

Hello,
so after i have connect my three yaskawa drives to my mesa7i97 and use the basic7i97.ini and hal-file from pcw i have test out something and have some problems.
I have installed the Linuxcnc 2.8 and update to 2.9 and it looks like after reboot i have more and more Network-Adapter-Icons on the Upper-Left.
Network is not working corerrect - no mesa-card found.
I quit these icons - so only one left and disconnect and reconnect network and now i have mesa-card found. This is weird!

Next is if i want to open "Show Hal Configuration" under Axis>Machine Tab - nothing appear... halshow on terminal shows only halshow.png not found. Is there some problems with the basic7i97 hal and ini files from pcw?

I want to configure now the drives - because the motors not move - but the encoders work correct if i move the motors by hand. I can also enable the drives - i hear a high frequency-sound and the motors still in position - if i want to move one over linuxcnc - the motor not moved - and of course the joint following error comes... (Have set Ferror to 1 for tuning)

So i have to configure the +-10V Analog Output but how? Is there a manual for setting the PWM correct to have the +-10V output?
I use the basic7i97.ini and hal from the posts here from pcw - but is this correct for +-10V?
