My next problem was that CWM, for some weird reason, did not have access to the internal or external storage. It kept saying "can't mount /sdcard" and there was no way around it. I eventually decided to try holding volume down when booting and using TWRP instead. From there, everything worked fine. I was able to format /system and flash the other files without problems.
Glad it worked now and sorry for your frustration. Is your sd card formatted in exFat or Fat32? What's the capacity?
