A couple of users reported that the closed profiles stay in TERMINATING state and then they cannot save profiles. They have to restart Kameleo to solve this issue.
If this is happening to you as well I suggest you to delete the C:/Users/<YOUR_USERNAME>/AppData/Roaming/Kameleo folder. That may solve the issue but we encourage you to send us a support ticket with your log files as well. Log files can be found in C:/Users/<YOUR_USERNAME>/AppData/Local/Programs/Kameleo/Logs
