x264 Error output in megui: Exception in readStdErr

Hi, I took a break from encoding for a few months. I started using megui again, updated it, ran a couple encodes and I keep not being able to see any of the stderror data I used to be able to see, such as the ssim calculation and the number of P,B, and I frames. Can anyone shed some light on this for me? (also please let me know if I should be asking this in the x264 forum). I have included examples of what I'm getting now (above) compared to what I used to get (below).

Thanks!

(On a side note, did the way crf is computed change or something? using the same settings I now get a much larger file than I used to when doing the same encode)
