I was working on this project for a week, and can't open it suddenly. It started when i added lighting and computations, but when I tried opening it on another computer there was no trouble. I reinstalled dialux evo 12, turned off antivirus/firewall, tried opening other projs (w/o lighting, wc was successful), tried the backup (.bak) file, and restarted the DIAL communication service, but still failed to load. I'm using windows 10. There were no error messages at all. I noticed when opening the "successful" projs, the loading bar at the bottom left loads all the way through. But with this proj that I'm having a problem with it, the loading bar suddenly disappears midway and then stays on the "start tab". Thanks in advance!
