I just installed updated Adobe AIR yesterday and now, when I
run any flash movie that is using actionscript 3 I get this
compiler error message:
Warning: 5004: The file 'playerglobal.swc', which is required
for typechecking ActionScript 3.0, could not be found. Please make
sure the directory '$(AppConfig)/ActionScript 3.0/Classes' is
listed in the global classpath of the ActionScript 3.0 Preferences.
