Help with reamping please

Please can someone help me before i start going more crazy. I recorded some guitar di tracks in ableton but exported to reaper because pro tools is a nightmare, if i try and reamp the di in ableton or pro tools with usb it sounds like a cab isn’t engaged and the stress sent me to reaper for ease. now i tried usb routing in reaper but the same thing like no cab is engaged, so i have now routed out of my focusrite output 3 mono into qc input 1 and out QC 1/2 output into focusrite 3/4 ( i hope that makes sense) my problem is ive got everything set up right on reaper and focusrite but every time i try reamping with the amp gain on 10 or 1 they both sound the same. I hope that makes sense and somebody please can guide me what im doing wrong
