I checked mine. From what I can see I have frozen:
-Exchange Service 0.2.17
-HuxEmailEngine 1.0
So the only ones I have enabled are:
-Email 4.1
-Exchange Services 4.1
Not sure which guide you used, but you might also want to check you set permissions correctly, etc. And just for your info, I used root browser light to delete the old apks, paste in the new ones and set permissions, if that helps any as well. If it still doesn't work, I can try to reflash Eclipse and see how I did it from there. (You will need to do this any time you re-flash the ROM.)
Good luck!
Also, here is the link I used. The files are attached in a zip on the OP, just download and unzip and copy them over:
