I recently uploaded a new sound. As it had trouble processing when I uploaded it the first time, I uploaded it a second time and deleted the first upload. However, the first upload was not deleted and therefore I had exceeded my upload time. Because of this all my tracks besides the latest upload were then hidden. I went to my hidden tracks and deleted the faulty upload so that I would have free upload time again. Now I should have 1 h of upload time left which is enough for my 6 remaining tracks to be visible. However, it says that i have only 30 minutes left and all of the six tracks remain hidden. How can I fix this problem?
