can i use my old eth addr? it is about 3 months old
Does it have any ETH in it? Make sure to do a split:

i dont have any ether on this account but also i cant see any etc on this addr, so i will delete all ethereum files from my pc and i will install new one ? i didnt use fork on my pc before
Yes, if you don't have any coins just start fresh with a new install and a new address.
