I have purchased 3 Mboxes complete with a pro tools express software. I have installed the mbox as instructed, I then download the pro tools software, and then the ilok key configuration, once the licence was downloaded onto the ilok key, I installed the pro tools express software, ran it and I get the unable to locate hardware message. I have reinstalled pro tools, with no change in the error message. I think I have followed all the complex procedures, but still nom luck, any help would be appreciated
