certificate erro

[gpa]

I try to install iSilo for my Nokia E65 but it gives me a certificate error. What happens?

Try going to 'Tools | App manager | Options | Settings' and set 'Software installation' to "All". and 'Online certif check' to "Off". You should now be able to install any compatible Series 60 3rd edition programs whether they are signed or not.
