That's a direct mount spider and not going to help you.
Honestly I'd just bite the bullet and spend the money on a different $30 crank W/22/32/42 installed and chalk it up to a life lesson. Worst case you also need to buy a $10 UN 26 or $15 UN 55 bottom bracket of the correct 122.5mm spindle length, but I'd guess your existing BB spindle will be close. Before you buy a BB you need to do some measurements to avoid a similiar issue of compatibility.
