igo8 problem

I have igo8 on my navman s30 the problem is this.
When it boots up it goes through the navman splash screen starts to load igo8 but then goes back to the splash screen again, and again, and again it gets stuck in a loop.
Anyone got any ideas.
Thanks Jock.

Are you currently using any unlock menus or scripts?

AppStartupSec.exe looks for an application window called SmartST_CE, If another window appears then it reboots the system, On Moov based devices the correct unlock is critical.
