First of all, I apologize for my English, this message is translated by a software (ouch, sorry)

in the temple of fire, shortly after the start, unintentionally I pushed a block in a path. The problem is that I can't go to the button to reset the blocks has their original location. I tried threw the objects (barrel, Round Rock) and I try to use the magical power "falling rock" on it, but it is not activated.

I played several time and have progressed in the game (I do all the Islands and secondary quest I discovered). I really want to start, I think I would leave the game instead. Have you a solution to offer me?

Thanks in advance

P.S. I put a picture to make you understand better, I surrounded the block and switch "resetting" blocks, and the path leading the switch is blocked. And the block not responded has no object I launch it :-/
Sorry it is a photo, I did not managed to take a screenshot (the result was a beautiful black background either a beautiful white background in 1080 p, I therefore took over the old method)
