FOCUSRITE FORTE: Help! Xtreme noise with PT12

Please help if you have any suggestions, I have just loaded PT12 and all the latest updates, however whenever I attempt to load any song into it, my Focusrite Forte makes so much noise, you would think that we are being invaded by an 'alien race!' I have a number of other DAWs that all work seemlessly with the Forte, I'm only having this problem with PT!
Any help would be much appreciated!
Thanks.
