Wound, a "Profile" is a personalized cache in the chrome appdata directory, it's what stores your personal settings and suchlike but it only truly matters on a computer with multiple user accounts from what I can tell.
Now stop singing the praises of Firefox in a thread where they're not wanted and get the forget out.
Anyway, as far as I know to solve this problem you'll need to delete your profile in the appdata directory, there are small guides on the internet on how to do this, but make sure you look up a guide on backing-up your bookmarks and such first as you will lose them when you delete the profile
