Hi,
I’m periodically getting this error as well (Error: Descriptor: FD#16696 not available’). Pardon me if this is an old thread, but this is the first hit when Googling this error. I’m on the latest version 5.2.11 and on Windows 10. Usually a reboot of the computer will fix it for a while (a couple days, maybe a week), but issue will resurface. Was looking for a more permanent solution. Is there a patch for this version?
Kind regards,
