Black roots are root rot. AV's should be planted into pots that are 1/3 the diameter of the plant and planted in a 50/50 mix of AV soil and perlite. Water only when dry. I water from the bottom until the top is wet and then I dump out all excess water. AV's don't like wet feet. There are times where one will need to water from the top to flush out all of the salts and accumulated minerals (I currently need to do this with mine). Leaves collapsing and curling are also a sign of root rot - I would take a couple of leaves and root them in water in the event you lose the plants.
You indicated that you repotted the crown - may I ask what was left root wise of the crown? My thoughts are that you need to cut the roots off until you see no rot in the stem of the plant and remove any rotting leaves, repot and then bag your plant in a ziplock bag - blow some air into it before sealing. You don't want the leaves touching the sides of the bag. You should see the leaves start to regain some turgidity. In about a month or so, you can remove the plant from the bag - acclimating it slowly to the air outside of the bag.
I have seen where a number of people like to wick water and swear by it - I don't. I never got that far and what I am doing now is working well for me.
An Eastern exposure is good - although my question to you is how cold does it get on the windowsill? I am in North eastern Penna and right now, my windowsills are still cold.
It is all a learning experience. I cannot tell you how many AV's I have lost in the past with my 'learning experiences'. You will get there and have gorgeous blooming African Violets before you know it
