You probably did it wrong o.o
how did you deprotect it.....
EDIT:
errrr I did it too o.o and I got the same thing you did.....but, dota's a bi*ch >:((
open the map in mpqmaster or something and check out the units folder
the slk files and txt files contain the custom units and stuff
Don't know if you can import that or something into object editor but if you can't you can just edit those files as is
(open slk in excel)
2nd Edit:
wellll i just saw owner's post (just a random post if you don't know who owner is)
go to
useful-tools-f69/some-must-for-your-tool-folder-t1921.htmland get the 2nd one (silk object console)
and that should be able to put it into object editor for u
