It's hard to know what might be going wrong here. We've tested the commands you referenced using the following version of OpenSSL, running on OSX: OpenSSL 0.9.8zd 8 Jan 2015 With valid values entered in the interactive Q&A, this generated a valid certificate that imports correctly into Burp. Can you double-check your responses to each question asked by OpenSSL, and ensure that you are selecting the correct key and certificate files in the wizard that imports the certificate into Burp?
