So i recently i transferred my project files onto a new hard drive. I have all my downloaded instruments and drum kits in the same folders however when i play them they don't make a sound. But it still displays them regularly, why is this and is there any way that this can be fixed. right now is my only solution is to find the drums and instruments and put it back in manually but if there's a more automatic fix i would appreciate if you could help me out. thanks
