I downloaded your bundle and edit it by changing all "Use_Display_Driver_Times" to "true", and now you can try the attached modified bundle which will not loading forever. For the first bug, you need to use the newUnit(a, "pressure", "pa"), Formula > Grids > Define a grid diagnostic, and type "newUnit(a, "pressure", "pa")", I am not sure "pa" or "pascal", you can give it a try.
