achievements problem!

[M1nn0w]

I am having a problem with the achievements on my x360. i have played more than 20 instant action games now in order to unlock the "goo god" achievement. the "spice of life" and "I see how it is" was unlocked as they should have but the other don't seem to work. i have the same problem with the "Lets get it on" achievement. i tried to hoste one of each, i played one of each on both ranked and unranked but still no achievement:S
for me collecting achievements is the funniest thing when gaming so this is a big problem for me!

I'm having problems too. I just took an hour to get the spice of life achievement and whaddya know, it didn't give it to me. Doesn't really ecourage me to try for any others now. Weak sauce.
