Cheers.Did you sort this out? Sorry, been without WiFi and data for a few days and only just noticed this.
You can check the android version by going to settings and then clicking on 'about phone'. This will show, amongst other info, your android version. If it's 2.3 then it's gingerbread but if it's higher then it's at least ICS.
If the phone is operating on ICS then I'd let the developer know that you have problems as they say they support android versions down to ics.
Of course, uninstalling and then reinstalling may sort it out anyway.
That's it then.
2.3.5
Oh well.
