H.264 Quality and Transcoding Problems After 7.1 Update

Question

Since 11/1, my CC manager has been telling me about updates for After Effects, Premiere, and Flash, but every time I tried to update, the update failed. (From the error message it appeared to be a corrupted download. It said to try downloading it again but there's no option to do that.)  I found that the main update for all 3 was to Media Encoder, so today I downloaded and installed the Media Encoder 7.1 update from Adobe's website, and then CC was able to finish updating the apps.  Now, when I use ME to render a Premiere project into H.264 format, the quality in general is awful, and any mp4 files in the project get rendered as a blank green.
Is there a way I can uninstill and reinstall just Media Encoder without uninstalling all of CC?  I've built up a lot of render presets and stuff in Premiere and AE and I just don't want to have to go through app folders and find all that junk to back it up.  I'm on Windows 7 Enterprise x64 with a Quadro 4000.  I did try rendering software only though and the same thing happened.  Exporting directly from Premiere instead of ME worked like a charm.

Answer 1

I solved the problem by downloading and installing the Premiere Pro and After Effects patches from the same place as the Media Encoder update.

It seem to be working okay now.
