Spotlife deb doesnt work for me?

[itschews]

It says the "The tweak you entered is not in the correct format."
I extracted the deb and tryed with the dylib then it said "Patching finished, the new iPA should now be in your downloads folder!" But there was nothing new in my dl folder?
I don't think i made a mistake cuz i watched a few tutorials
edit: other debs dont work either and dylib no output
