I am relatively new here and asked this question in chat but so far no help. I have no particular reason to think I have been hacked but my keys are not working. The posting key works in autosteem, but I tried the required keys at steepshot and also at blockchain when trying to buy some delegation, in both cases the keys were no good. Should I be worried I have been hacked? If not why dont the keys work and how can I get ones that do?
