but my Finder won't recognize it even though it presents me with the correct "Hint"
I reinstalled Yosemite and created a new user password. it opens my computer but my Finder won't recognize it even though it presents me with the correct "Hint". Therefore, I can't delete documents in my disk, download applications, or access any of the locked system preferences (like changing the time)
iMac, OS X Yosemite (10.10.2)
