Circuit Maker uses spice. What do following messages mean?! Float overflow exception in simulation. Warning: singular matrix: check nodes lakt1#branch and lakt1#branch Warning: source stepping failed doAnalyses: Matrix is singular thanks

You most likely failed to include "ground", a node numbered 0 (zero).
Most "Spices" tend to give utterly meaningless error messages... just like Windows ;-)

I love to cook with wine. Sometimes I even put it in the food.
You may have a floating node.

"Matrix is singular" -- plus the 'node' being the branch current equation associated with an inductor.... Makes me think either the matrix package didn't manage to remove the zero from the diagonal -- do you have a tree of inductors? -- or that you have a voltage source/inductor loop.
Yes, I have a Transformer and an inductor in my circuit.
