For some reason SLAM has stopped working as it should. Even when it's not running I can run the commands as normal in TF2's console and load files, but no matter what I try to load it plays the same distorted high-pitched noise for all of them.

If I try to load a sound through SLAM it's not recognized in-game, and if I refresh SLAM it notifies me that the sound isn't loaded after all. The only thing that's recognized in the game's console is if I add or remove sounds from SLAM's folder, other than that it's like there's no communication between the two at all.
