I too struggled to move my mast step. I believe what happens is that the machine screws are so tight into the solid glass, creating so much heat, that they recure the resin each trip in! I believe that resin hates heat (ironically) & so you will have luck with a torch. However...please DO have a bucket of water handy!!!
Mine proved difficult with an impact wrench but it came out. I would recommend that you install new screws after you move the step. Mine are pretty worked over after reinstallation. Getting them back in was not a ton easier than removal.
When you get the screws out, you'll see that all we have are incredibly long screws run into solid glass. I cannot advise if it would be wise to increase the diameter of at least some of the pilot hole but it seems like it be easier to move the step if so.
