Update driver-rutins UR44

All of a sudden I cant get any signal in Pro Tools vst instrument. I cant neither get any midi-data thru my Steinberg UR44. I guess that I have to update my driver-rutins for my interface (UR44). Anyone know how I`ll do that?

Thanks for the help

A signal suddenly not coming thru has nothing to do with drivers imo.

However, you can check and download firmware with installation instructions from Steinberg website.
