The email I received with voucher codes for GNS3 and Python after passing certification exams is a welcome, but mixed bag of goodies. The voucher code for the GNS3 class (part 1) comes back as invalid.
Sorry to hear about this. Have you tried to emailing certification@solarwinds.com?
Did you get any good solution, I think I am facing similar kind of problem.
