Error Verifying License - Android Simulator

Hi,

I'm trying to execute my application on android simulator but I get the following immediately when the app launches:

[WARN] :   dalvikvm: threadid=1: thread exiting with uncaught exception (group=0xb1d2db20)
[DEBUG] :  dalvikvm: GC_CONCURRENT freed 1010K, 12% free 8420K/9504K, paused 15ms+1ms, total 23ms
[WARN] :   TiVerify: (Timer-0) [5079,5079] Verifying module licenses...
[WARN] :   TiVerify: (Timer-0) [21,5100] Error Verifying License

Any ideas?

Thanks, Fernando
