Birthday present - not so great

We started it up yesterday. We had a couple of glitches but were able to work them out. Then it worked for about 45 minutes and the same glitch came up. We couldn't fix it this time. I emailed the place and got an answer today. They gave us several solutions all of which we tried but it still didn't fix the problem. They are going to email me back and tell me how to exchange it for a new one. I hope this works out because it was doing a really good job and would make my life so much easier.
