    Try the new chain on the existing chainrings. See if it will fit over the teeth and also if it can fall between rings.

    My expectation is that your existing crank is fine. If it's not, you have a few options, depending on what the problem is.

    You will be fine as is. I've got a M660 crank modded to 2x, ie. M665-ish running 10 speed w/o issue.
