The error I get from the first program is arc move in concave corner cannot be reached by the tool without gouging. I also see that you set the tool table but fail to load the the tool length offset with G43 so I assume your not using that. I'd have to say (without laying it out in a cad program) that your lead in move is one that creates a concave corner. I'd suggest an arc move into the large arc or one that is more aligned with the path of the arc.
File 2 is an easy fix, move the G41 above the G0 xy line so the lead in move is a x and or y move that is longer than the radius. A G41 then a z only move cannot work.
