Issue with reconnecting

Hi, Thank you very much for the app. I have used it connected my force plate once, but after a while, when I tried to use it, it cannot connect to the force plate. The error message is "Could not initialize the AMTI interface: Device is reporting a change in the number of connected force plates. Please re-try". I have tried a few times unplug and re-plug the device, but didn't help. I selected the correct port and sampling rate 50Hz. Do you have any idea why this happen? Thank you.

I got this solved, but another issue appeared. It's connected and no error pops out,, but not actually pulling data. All I got was zeros ... Do you know why could this happen? Thank you very much.
