Many times the Program (User interface) doesn't load up correctly, I can see it run in the Task Manager, but the Interface doesn't show up, or it does but stays blank.
I know about the workaround to delete C:\Users\"username"\AppData\Roaming, and sometimes it works. Cam starts, log in screen shows up only to stay sometimes blank after I logged in. I have to repeat the process a couple of times to get it working, after that CAM continues to work properly for multiple days until it doesn't.
