Could not Compile Application Class

[Ray]

I'm in Livecode 6.6.2, the most recent stable version, on Windows 8.1, 
and I'm getting an error of "could not compile application class" when I 
try to save as a simple "Hello World" standalone for Android.

Sounds like something you'd see in Visual Studio C sharp or something, 
not a very Livecode type of an error.

Any ideas?
