[Q] E: Unable to mount '/cache' topic

I just updated to TWRP 2.6.3.4 on my Sprint HTC One, in order to flash KitKat, and the corrisponding CyanogenMod Nightly's, but in doing so I wiped everything off my phone. So now I can get into TWRP, but have no ROMs to flash... I tried sideloading, which didn't work, so then I just used adb push to get my files into data/media, which worked.

Now Im trying to flash the .zip files for KK and CM11; KK flashes just fine, but when it gets to CM11, it gives me errors like:

Code:

---

E:Error executing updater binary in zip 'data/media/cm-11-20140129-NIGHTLY-m7spr.zip'
Error Flashing zip '/data/media/cm-11-20140129-NIGHTLY-m7spr.zip'
updating partition details...
E:unable to mount '/cache'

---

Failed

I've tried flashing KK before CM11, and after CM11; but no matter how I do it, it fails on CM11.

Anyone know whats wrong with my phone? How do I fix this so that it'll flash CM11, or any KK ROM?

Any help would be great, as my phone is useless right now...
