Don't worry, I'll feel better and get back into it. 
I felt super defeated earlier, because it felt like things had been getting better, now it feels like I've been wasting my time; but I've appreciated all the help, more then just 'thanks' can say. Thank both of you, for your help AND your encouragement.
They're always nice, so poke me if you ever need the same. As for that - good idea!
No dice, so far. I tried with Open Shell removed and after a restart too, just in case. I'll have a think on it..!
