Weekly Update Not Finishing

[mAzco333]

I downloaded the latest weekly update and installed it via TWRP. Then I installed SuperSU. When I rebooted the system, it started as ususal. But it is stucked in finalizing (I don't know the exact translation, in Spanish it says Finalizando) 100%. It has been in the same point for a while and I am getting nervous
Do I have to wait even more? Could have been any problem? If so, how can I fix my phone?
Help please

Edit:
Now I am redownloading the zip file (just in case) and then I will reinstall.

Edit 2: Problem fixed thanks to Netanelk

Wipe dalvik cache and cache via TWRP and try to instal the rom again... (not full wipe)

But how do I wipe dalvik cache and cache via TWRP if the phone is stucked in finishing the update?

Edit: already wiped the delvik cache and cache. Now I will reinstall

Edit 2: problem fixed. The phone is working as usual and updated succesfully
