I have a couple of 55/40's and I find both of them get cranky and difficult to open if they have not been recently lubricated. If you haven't already done so, try giving it a little oil and see what happens.
I doubt that you're dealing with a serrated pin in that lock, probably just a couple of mushrooms or spools. Both of my copies seem to have two spools in them.

I press down Pin 1, get fault set.
Pin 2 binds, I press down pin 2, get counter rotation, and when I set pin2 the pin1 pops out again. If I set Pin1 then Pin 2 pops out again.
What am I doing wrong?
Is the binding order completely different? I picked this specific lock a few times and I began in the back with pins 3-5.
Remember: I am still a beginner.
I think Wizwazzle made a vid about this phenomonen (setting one pin drops another, setting that one drops another) specifically in abus locks. If my memory is not faulty he used the 55/40 as the example in the vid. He calls it "abusitus" and recommended good lubrication, and cleaning if necessary.
The binding order that you experience with a lock can change somewhat depending on variables such as amount of lubrication present, how tension is being applied, amount of tension etc.
Just don't let the lock get you too frustrated. Do whatever you need to (take a break, pick an easier lock for a confidence builder etc) to calm down because once you're annoyed with the lock you will not be at your best.
