Just got my new cutter today. The MH 871-MK2. Had a few issues but seemed to get them worked out, it is afterall, new to me. Familiar with cutting and making signs and label, and heat pressing. That all done from my Cameo. Now time to move up. I can cut, but each time a message pops up saying your software is in Demo mode and you will experience horizontal lines thru your cut. UGH!! I have no clue how to turn off the Demo mode. Can anyone help me?? Thanks in advance
