Hi! I got this message from klab saying "該当のアカウントを失くした時の状況を詳しく教えてください"

I want to tell them this: "I'm a returning player so I didn't know about the new SIF ID system, therefore, I didn't connect this lost accout that I'm enquiring about to an ID when I acidentally restored some old data from a different ID."

Could you please help me? It doesn't have to be exactly that in translated form, just the gist of it should be fine :).

Thank you!
