System error -1 in deveoper certificate sis not in self signed certificate Problem??

Hi,

I have a strange problem. My sis is working fine on device if i self signed it but when i signed with the developer certificate it gives me system error -1.

Need help..

Experts Please advice me in this regard..

Thanks,

did you change something on sis or code level ? then check what those changes were and how they could behave.. Also you maybe could try debugging the code to see which line is giving the error.
