Hello,
I have a problem with IOTA, i have created a new seed in the beginning of the last year, to move my funds from an old seed. I have used that seed just few times, once to attach an address, and other time to verify they arrived. Now, after many months, i have installed the trinity wallet, cuz in the old wallet i have zero balance in all seeds, and the seed is emty, nothing, even in transaction history. What else can i do and why this happend in the first place?
