Same thing on my end using build 365. Got past the point of rendering and then a popup come up that asks me to select an output audio format. I chose the name of the file and the default format of MPEG Layer-3 and the attributes of 56 kBit/s 22,500 Hz, Stereo 6kbs/sec. I click OK and it comes up with another popup window saying Driver Cannot cannot do the requester conversion. I wound up with a wav file that plays OK but that is not what I asked for. I asked for an MP3 file.

Using Windows 7 and standard MME for my audio settings. I actually noticed this when the 2013 update came out but did not post my concern.

In addition, I tried this on my Windows 8 HP Laptop and got the same thing using ASIO4All

I even went as far as putting the Lame encoder in my BB directory with no difference.

Also, why is 56K at 22,500 Hz the only choice I have for MP3 output. Not even CD quality.

WMA works OK
MP4 works OK
M4A works OK
MP3 does not work for me at all.
