hold up, steem is getting broken

So last week I noticed something when I tried to log into my Steemit account with my posting key.

At first I thought I had inputed it wrongly so I went back to check. To my surprise it was correct.

I then assumed I may have accidentally added or removed or replaced a word in the back up since it was a simple doc file.

Since then I have been using my master password to log in on my computer.

I have to say that I have multiple backup of my keys in different secure places, most in PDF uneditable format, so I am safe.

I also need to mention that I have been signing in with my private posting key for ages now and have had no problem until last week.

So fast forward a few days, and a community member of mine complained about being unable to access his Acc, in his own words, he posted after a long pause, and as soon as the Steemit terms and conditions page came out, he accepted and boom, he could no longer access his Acc.

Now in his case, there are many factors to consider.

But he too had a backup, he couldn't use his master password anymore as that was what he backed up. So he may have made an error while backing up and backed up the error along aide, no biggie.

Today now, I am no longer on the laptop and just now posting via my phone, to my surprise, my PDF unedited backup of my keys, which has long been working refused to work on busy.org.

I'm scared and worried and that's why I'm putting this post out.

Today its my posting private key, which may I remind you has worked in the past and was what I used to access Steemit 2 weeks back is no longer accessing Steemit.

What else could happen? Could my master password be next? Who else is in this shoe.

What's happening?

The error I keep getting is "wrong password/key" or along that line.
