Going after the solution step by step:
1) Make sure you have acquired a developer account from Apple that costs 99$ per year.
2) Make sure you have Acquired a hosted Mac builder user ID from Erel in order to be able to compile without a local mac
3) Make sure you have configured the paths
4) Make sure you have entered the correct hosted mac builder Id in server settings.
5) Make sure your Apple Developer account is activated.
6) Follow step by step the way Erel describes in
www.b4x.com/etp.html (or .htm - I do not remember) in order to create the certificates and provisioning profile.
7) Replace the way Erel gets the UDID of the device with the acquisition of UDID from iTunes in your local computer (google it to see how this is done).
