You said that "I logged in with my old account". Is it possible that you have two different Evernote accounts? Best thing to do is to login to the EN Web client at Evernote.com and see if your Notes are there. If you might have multiple accounts, try logging out of the EN Web client and logging in with other account email. With EN Mac Ver 6.0.5, your Notes should appear shortly after you upgrade, no more than 1 hour. The database reindexing might take a while, but you should see some Notes almost immediately. If no Notes appear, then most likely you have signed in with a different account. Hey Michael, Thanks for your help! It turned out that I did sign in with a different account, strange, because I did not remember signing up for another one. All my notes are still intact, thank goodness. Thank you again!
