Bit of a bummer for you as this is a known issue with those cranks. In their quest for stiffness they have beefed up the spider by a few mm thicker and on frames with thicker stays they strike.
Depending on your frame material you can have the stays pinched or crimped. Best check with a pro on that for advice. Otherwise you need to get another set of cranks and a new BB by the looks of it.
