Ok, I will try to add the sub VIs, I am just not sure how many layers of these I will need to add.
As the VI calls a sub VI who calls some sub sub VIs etc. (I haven't created the system myself).
I haven't played much around with the settings, I am merely trying to upgrade the system from 7.1 to 8.6 - an act that proves far more interesting than I had anticipated. When I am done(thought I was nearly there when I got it running in developer mode) I will have to also upgrade the TestStand from 3.1 to 4.1 - Hope it proves more easy than the LV upgrade...
