sort of a rat's nest. I got byteball wallet to pop open last time, participated in giveaway. Went to check it out, had to get new wallet. So I got a huge library of new files and nothing indicating to me what the wallet is but when i go to search in menu of linux, i got what must be old byteball and it just repeats error. Is there some indicator of what the wallet client even is to open it up?
Did you backup your wallet files when you upgraded and saved the seed also?
