I have a similar situation - not related to billing, but submitted a technical support ticket well over a month ago - no response. I don't have the ticket # handy here (I"m currently at work), but tried to PM you about it Ryan - and received a note that you're not able to receive PMs. Am I doing something wrong?
UPDATE: Ryan was kind enough get in touch wtih me via PM and gave me some workable solutions. Also, it looks like I never actually submitted a tech support ticket, but errorneously entered my question inot the 'other comments' section of my profile when attempting to submit the ticket. So Cakewalk wasn't to blame - as usual, (as my wife would say), it was my fault.
Apologies for any confusion.
