If you open your main menu, and go to "Point Allocation," you can click on "Re-Assign." That will allow you to reassign all the points you've previously allocated. Depending on how many points you've already allocated, you may have to click on Reassign, then wait a few hours to click on Reassign again, before you can reallocate all your points. But it seems unlikely that you've already hit physical level 50, so you'll probably just have to Reassign once or twice.
