Yeah it seems to be a windows 7 related issue, as far as i can tell no windows 10 users have the issue. and friends i play with on windows 10 load character screen super fast. I installed tequila and the game and never had COH on this pc. Deleted all folders and reinstalled it once. Since others are having the issue i doubt your old files are effecting anything. Will you ever have a use for old live files... Maybe someone with more knowledge can shed a light on the for ya.
