error with App.isRunning() - only available in 1.1.0+

[Brad]

Trying to implement a check that intended app is running before working with it (and open if not).
Followed the example from the docs but have the following error...

[error] AttributeError ( 'org.sikuli.script.App' object has no attribute 'isRunning' )
[error] --- Traceback --- error source first line: module ( function ) statement 825: main ( loadMyApp ) while not myApp.isRunning(5):
[error] --- Traceback --- end --------------

myApp = App("Example App") <-- this is called at beginning of script
myWindow = myApp.window(0) <-- this too

The script runs, but I've always ensured the window was open before running and if the app crashes the script would eventually exit as I have error checking on failed find attempts etc. Just wanting this as a backup to try and restart the app without manual intervention.

I am using Sikuli IDE 1.0.1 (build 12SEP2013160242 from the about window) on Windows 7 (64bit) if any of that is important.
I've done the "Help --> Check Update..." but it returns "No update is available"
