DTube - login issues...please HELP!

Hi Steemit users -

Please help a brother out... I'm not having any luck with DTube log in...

Do I use the same credentials for DTube as for Steemit? I keep getting the error message that the password/key is not correct (as per below screen grab). I'm trying to post a video for my blog but can't seem to log in.

I also tried going to the steemit chat channel but it too gives me an error message when I try to log in.

Kind thanks for all your help in advance!
