Importing pictures from CANON 70D

Since I upgraded my iOS on MAC my Bridge cant get the fotos from my Canon 70D. At first i couldn's do it at all, because the information I had was that the camera didnt have files. But then after trying a coulple of times i was able to see the icons of the pictures. I tried to rename them as I always did, but it only imports about 5 pictures, then there is a popup saying that there is an error.

I tried another camera (Sony ALFA350) and it worked perfectly. Only canon gives me this problems.

Please help me because I cant find a way of making it work, and I searched on other foruns anf I cant find an answer.

Thanks.
