Audition Won't Fully Open My File

Has anyone else had a problem where Audition will only open the first few seconds of a file? I have an audio file that's around an hour long, and it will open and play fully in other programs so I'm fairly certain it isn't a problem with the file, however Adobe Audition will only open the first 9 seconds. Is there a simple fix that someone has come across or is this something that only I'm running into. Any answer is appreciated. I've tried it in Audition 24 and 25 using Windows.
