Actually the error can be seen in the project you sent me. For some reason it recursively copied the projects folder.
I'm still not sure what causes it.
Does it compile properly if you reinstall B4i in the default location?
About the second error, it looks like you haven't created the keys correctly. In such cases it is simplest to delete all keys and start from scratch.
Note that you don't need a development certificate at all. Use a distribution (ad hoc) certificate.
