hmmm, you did claim and post a video 12 days ago?
If you truly lost your key, you know there's nothing I can do for this testnet, you'll need to redo it with another steem acc if you wanna play with DTCs.
However you're not the only one with this issue, so yes we will do a process for people in this case before the start of the main-net, so that your mainnet account starts with another master key. Will be announced in the @dtube blog before main-net launch.
yes i did and yes i did lose it somehow... meh ;x
