Your sprocket is possibly bent or has the wrong size (or no) adapter. It always happens when the cranks are pointing a specific direction, right?

You sure the sprocket is good? Does the alignment problem occur when the cranks are pointing a specific direction, or does it change every time? It could also be a stretched chain.

Doubt it. It's most likely the chainwheel being bent warped or out of alignment.

Sweet. For now. take your current sprocket and put it on a flat surface. Put a block of wood on it and beat it with a hammer till it's straight.
