Hello Jim,
Thank you for your question about changing ID's. It looks like our site picked up the name change from 'tradingcompany' to 'coin', but there is a second account starting with 'newengland' that shows a recent login this year. The accounts have different email addresses, which could be affecting the login.
Could you tell me the status each account? Are you using both on eBay? Could one be disabled or closed? Let me know and I can decide the right action.
