Can anyone help with this setup - I run SD on a Macbook Pro with Parallels.



Lately it has been getting hard to get SD to open. I open Parallels, login to Windows 7, double click on the SD alias. I get a little blue circle for a couple of seconds, then nothing. Up to today, i would wait a while (frustrating, I want to go flying!) and then try again. SD would usually open, and i would find I have 2 versions of the programme running. (How is this even possible?)



Today, I can't even get it to open at all.



I've tried downloading v2.2 again, but I can't get W7 to re-install it. Double click on the installer, nothing happens.



I'm somewhat hampered by being unfamiliar with Windows - I got Parallels and W7 solely to run SD.



Can anyone suggest anything please?
