As above, my megatune for some reason decidedit would stop opening for me.
Hit the icon, select 'with AFR' and then nothing. The Icon comes up on the task bar thing on the bottom, but wont open.
Whereas if I select any other of the options, like 'with MAF' then it will open fine?

 

Mine does the same thing, but tunerstudio works perfect for me and I use that anyway.

 

If you're using Vista or W7 try and right click and "open as administrator"

 

Also, if you're on a laptop and have ever used a second monitor, sometimes the window position gets fubared. right-click on the program in the task-bar and choose Move. Then use your arrow keys left and then right if you don't see it. It might be opening, but not where you can see it. lol. This DID happen to me and I was more than a little upset until I figured it out. lol.

yep. i was going to suggest it was open but beyond the screen...happens to me often with my dual monitors and when I VPN in.
