Merging 2 Gmail accounts

Hi! I have backed up both of my Gmail accounts with Gmail Backup. Worked perfectly. Since Gmail has upped its account size, I really only need one account, so I restored the emails from BOTH accounts into one. Problem: ALL emails from Gmail account 1 seem to go directly into the trash bin in account 2 (save for the ones not older than 30 days). How can I get account 2 to recognize the emails from account 1 as legitimate emails? This would seriously help me.
