How you do continue working with support when they're not responding? I'm experiencing the same issue. They e-mailed saying my RMA was approved and that they would ship out a new unit and requested my address. I replied with my address and haven't heard anything for 4 days, not even a "we've received your e-mail and are processing it". I sent a second e-mail asking if they received the e-mail I sent, with no reply to that either.
