I say stick with the problem and learn to love it. Since mathematics is so interconnected I'm sure you'll find your way.
It would help to learn about the history and context of the problem. Why did people invent this big machine? How does it relate to cool things in math that you do like?
Suppose you would change topic, how would this be different? You can always say something is too technical and not of interest. It's far better to take your topic and find a piece that does seem interesting and is not too technical (when looked from the right angle).
