Version 4.10.3 Package error

Everytime I try to package my demo it says error package failure, I tried copying the content onto another project but it didn’t work, I tried to restart my pc but nothing!, the packaging failed more than 5 times please help, a log of the error has been attached to this question link text

I found it, it was the “Horror Pack” from the marketplace, the creator misspelled blueprints, all you have to do is change “bluprints” to “blueprints”
