Stuck during native app generation


Has anyone ever seen the developement environment get stuck on:

Preparing to generate Android Mobile App...

If anyone knows where I might be able to cancel that process that would be great. I am developing an app and hope to showcase to a client in a couple of weeks, I cant afford a full license until I get that first customer so am doing this in the free license I'm afraid!



If anyone knows whether I could just export my apps, delete and reimport - if the free license will allow that and if that process would actually forcibly stop the compiler (probably the wrong word, builder? whatever it is that is stuck!).

Its really stopped me and have had to prematurely switch to work on the interface (so no time lost really) but it just worries me that if it cant be fixed I'll need to rebuild everything from scratch.
