Hi all! 

I've just started having this problem with Active Sky for P3d V4 - when I try to open it, I see the splash screen but the UI never shows up. I can see it in task manager for a few seconds, then it disappears. Can't get it to start. 

Any ideas please? I've tried reinstalling AS and running it as an administrator without luck. 

Thanks!

Found a fix, just had to delete the 'Lastdownloaded.wx' file in the ASP4 directory. 

That's great. Here is the KB article if anyone is interested.
