I've been using ChemDraw occasionally for the past few months & today the app refuses to launch. It prompts for the registration info (serial, etc), then once I accept the folders suggested for templates etc. in the next window the app fails to launch. I've uninstalled and reinstalled & still have the same problem. I haven't updated my OS, installed any software, etc since the app was last working. Does anyone know a fix for this?
