SCirce

I've spent 4 hrs now trying a buncha different things and cant figure it out. I've got the green light on the ECU, when I plug in the USB my computer makes the sound but it wont connect to PC Link. If I go to my Device Manager I can see it come up on the com ports but it has an exclamation point next to it. If I click on it it says "Drivers are not installed or needed for device" and if i search for drivers it doesnt find anything. I've tried manually selecting the com ports in PC Link and tried different Baud rates to no avail. Any help would be greatly appreciated.
