it stopped working when i turned off the speakers and disconnected the midi cords to my keys. i did this to try to fix another problem which was my mod and pitch wheels were moving in garritan and screwed up the sound

Are you using a soundcard? You said previously that you didn't have a usb connection. I'm assuming you have a sound card like maybe an M-Audio soundcard that has a midi in and out, and that is also supplying the audio out to your amp and speakers?
If so, I suspect in your computer it must be selected in the control panel(windows) as the default sound device, and it also must be selected in pro tools, and also any standalone software. If you don't have the option of selecting the soundcard either in the computer control panel, or the softwares it doesn't show up, then you should delete and reinstall the soundcard drivers. Older M-Audio soundcards can be a pain sometimes, the webpage of whatever soundcard you have should have a list of current and archived drivers. But check first to see that it is the default sound device in the control panel.
This part of the video shows you where you would select your soundcard. If you need to know how to get to this sound device panel, just start at the beginning of the video. If your soundcard is not listed as an option, you will need to reinstall the drivers.
