How do import a paper private key into MultiBit? Sorry to sound like a total Bitcoin noob (which I am).
I've just made a purchase at the new Robocoin Bitcoin ATM.  I have a paper receipt that has a Private Key (starting with 5 and 51 characters long).
How do I import this key into my wallet? I'm using MultiBit 0.5.14 on Ubuntu.
Thanks in advance!
Tools -> Import Private Keys

Create a file with the private key inside it. If you do not add the time of creation of this address, you get this message:


  "There were missing dates. Have to go back to genesis block."


I think this date should be the first transaction date registered in the block chain.


  Key createdAt is in UTC format as specified by ISO 8601
  e.g: 2011-12-31T16:42:00Z . The century, 'T' and 'Z' are mandatory


To be safe, turn the date back a few days.
