Hallo Stefan Thanx for your reply. I think it helped, although I don't think my circuit is working yet. What does following warning mean? WARNING: TR1: inserted virtual resistance at node `_net1' connected to [XLM317.X1.X1.Q2,XLM317.X1.X1.Q3,XLM317.X1.X1.Q4,XLM317.X1.X1.Q5,XLM317.

X1.Q25,XLM317.X1.X1.Q26] Get it like a thousand times. Couldn't get any of the other circuits running either. Guess I have to try some more. Cheers, Ezra.

It just means that your node _net1 (a node which you did not give a label) is floating (not connected to some definite potential). When you have a specific schematic which you can send to me I could probably help you solving the problem in case you have a expectation what should actually happen. > Couldn't get any of the other circuits running either.
