Having syncing issues with multiple macs....

I just picked up a new 13.3" MBP and added my mobileme account to it. During syncing, I chose the "merge all data" option as I normally do when I reinstall OS X or what not.
For some reason, it synced everything except the contacts, which it wiped from mobileme, and my iphone.
I thought all my contacts were gone, but my old 15.4" MBP hasn't synced to MM yet, so all my contacts were still on it. I did a sync thinking that MM will get confused and ask me what it wanted to do, but it didn't, it just finished syncing. All contacts remained on the 15.4" MBP, yet no contacts were showing on me.com.
What am I doing wrong?
All my contacts are still showing up in the address book on my 15.4" MBP, how do I get those to my MM account and then onto my new 13.3" uMBP and iphone?
