The program was working fine until I exited and then tried to reopen it. The Audacity logo appears on the screen then disappears and nothing happens. When I try clicking again it says that Audacity is already running even though nothing is on the screen. Then, when I unplug my Rode NT1 from the laptops USB plug in and try running Audacity again, it launches and the program appears on screen. If I plug the mic in AFTER Audacity is up, it won’t read it. Help?
