Universal Laser V460 - computer upgraded, engraves but won't vector cut

Hello! I have two ULS V-460 lasers, and both have been running for a long time connected to a Windows 10 pc. I replaced that computer the other day with a newer Windows 10 pc, downloaded and installed the newest ULS drivers, and strangely - my vectors will only raster. I've tried different line thicknesses and made sure I'm using the ULS color pallete. For the life of me I can't get a vector to cut! The lasers will just raster everything - even the thin .001 lines that are meant to cut. I am using CorelDraw 19. Does this ring a bell with anyone? Thank you for any suggestions!
