O.P. HELP - Interfaces!
I've uninstalled, reinstalled, repaired... and it's not to do with having Windows Live Messenger 2009, because the problem originated before then.
I am unable to create interfaces! If I duplicate a perfectly working window, or directly copy a window from the Scripting Documentation, or write one myself that should work, it doesn't.
In a script, nothing happens. No error, no debug message, nothing. Using the Interface Tester, it comes with "Error loading XML file". What's wrong with it?
