Possible to escape openStack?

[Kevin]

Oops! I've managed to create a loop in my openStack script which pops up an answer dialogue then, on OK, quits the stack every time I open it. Is it possible to get at the stack script to alter it or do I just have to bite the bullet and go back to my previous version and start again?

It's an iOS app and I'd forgotten to put in a line to escape if the platform was not mobile
