One of my employees reset my HD and i lost acess to my wallet, there is a way to backup my wallet just with my old seed?
When I try to  Accounts> Import Wallet and > Import Seed, my seed gets red, why's that?

I have downloaded the rai_wallet and let it synchronizing the blocks while i go sleep, but when i wake up my wallet was locked but i didn't put any password on it, so i can't unlock.
So I copy my seed and reinstall my wallet, can anyone help me how can I open on my new wallet  my old seed without any password?
