OK this is what I did that seemed to work, done with latest version of Aspire BUT there should be no difference between Aspire & Vcarve for this.
Opened your file
Rotated the vectors
Recalculated all toolpaths (not individually but using the recalc icon)
Went back to drawing view & used the job set up to alter the material size & x y datum position, clicked OK
When message to recalculate poped up I hit yes, all toolpaths recalculated OK
Selected all vectors & hit F9 to centre everything
Went back to toolpath menu & hit recalculate all toolpaths again
All toolpaths seemed to recalc OK only got the material thickness warning come up.
I didn't preview the final toolpaths but everything else seemed to work OK so no reason why it wouldn't be good
