I can't log in to sync my account

I installed Firefox on a new computer and tried to log into my sync account to migrate the data over. When I put in my email it keeps telling me that the account doesn't exist. I verified the email address on the old computer and it's correct. I even tried to reset password but when I put in the email address again it said it didn't exist. I created a new account with the same email address with no problems. I just can't figure out how to migrate all my data from my old computer. Thanks in advance for your help.

hi LePlane, this probably means that you have used sync on the old pc for a long time, because there was a new sync/account system introduced in firefox 29. please update to the new sync on your old pc to transfer your data successfully: Sync your Firefox bookmarks, history, passwords and more
