UNABLE TO DOWNLOAD SOFTWARE

I signed in, typed in my license code and was told it was already associated with an account and to go to my downloads.  Went to downloads and it isn't there.  I have tried multiple times.  Requested help, got a number and a confirmation code and shortly after I called I was cut off.  Called again and got automated questions.  Was sent a link to help me but it is for Windows and I have a Mac.  I need someone to help me so I can get these done!!
