Bernina Activa 131: Feed Dogs won't come back up

Question

I just bought a darning/quilting foot for my Activa 131 and decided to try it out. I initially forgot I had to lower the feed dogs to use this foot, so I started using it with the feed dogs in the normal position but immediately realized that I had forgotten to lower them. Wel, I lowered them and experimented with my new foot for a while, but when I tried to raise them again they wouldn't come back up. I turned off the machine and then turned it back on to see if that would work but the feed dogs are now stuck in the darning position. Is there any do it yourself solution to this problem or do I have to take it to a professional to get it repaired?

Thanks in advance to anyone who responds:)
