So today I finally finished the Hall of Meat challenges and waited for my "Spare Parts" Silver trophy, almost an hour later... nothing. This got anything to do with me downloading the recent DLC?

Either way, I'm not happy... anyone got any suggested fixes?

nope, shouldn't be the dlc. though, for me, i thought i had finished everything and i had actually missed one of the top tier challenges. try redoing the last goals for each category (if you can).

i somehow had missed the easiest of the top tier challenges so i was just 're-doing' them when it popped up. give it a miss at least before you give up on it.

i am having the same problem but i HAVE 100% done all HOM challenges,  i have 15/15 of each and i have done the last ones multiple times for each and yet i still dont get the damn trophy... its really getting on my nerves now and i don't know what i might do to the disk!

I was able to unlock every single Trophy but the "Freeskate" (Silver) one (and I guess the Platinum as well, because of it, of course), so I know it's possible.  I don't recall running into any glitches, but maybe it does have to do with the DLC, which I believe I did this one beforehand. 

I wish I had a fix for you... but, if anyone ever wants to try and get the "Freeskate" Trophy with me online, I'm down! :) 

few days on and i am still not able to unlock it... (i wont move on to the multilayer trophies if there is no point if i cant get this silver) unless i go through ALL the HOM challenges again (even though they are crossed off) to see if it work, it looks like i might have to start a new game :/

I got all of the free skate activities and the game didn't give me a trophy for it :(

Way to go black box.
