Maya is only rendering 1 frame over and over
 

Hi, I'm trying to render out a few frames in Maya, for example start frame: 240 and end frame: 265. The entire scene is 340 frames. Whenever I batch render, Maya renders out one single frame over and over again however many times.
Earlier on, I rendered out all 340 frames using Maya Software, but ever since I changed it to mental ray, the batch render hasn't been working properly.

Thanks for your help!

And the only thing you did was change it to MR?

Yes, and ever since that happened, when I changed it back to Maya Software, it only renders 1 frame over and over.

Edit: Nevermind, I started over and it seems to be working correctly again. Thanks!
