After handing a file back and forth a few times, my preexisting reference markers have lost their arrows, and new ones are being created without text fields or arrows. Any Idea how to fix this?

I have been using Vectorworks on a new, to me, PC with no problem for the past two months. The PC has an AMD Radeon R9 200 series graphics card in it. I recently was prompted to upgrade the driver on the Graphics card and since then VWX has been almost unusably slow. Simple actions like moving 3d objects force it to spin in place for 5-10 seconds every time. I don't know if the graphics driver update is really to blame but it is the only thing different I can think of. Any help or ideas to improve performance would be greatly appreciated. Thank you.
