Update not working.

Hello Developers. I am at a loss. I am trying to update my app to a new build but Transporter keeps giving me errors. My question to you all is simple I think?

1. Do I need to create a new certificate for an update?
2. Do I also need to create new Identifiers?
3. Do I also need to create new CSRs?
4. Do I need to also create new mobile provisioning file?****

I am sending a new IPA file but it keep crashing transporter with errors about the build?

Ugh. Any help would be great.

Thanks,

JC
