Why can't I login on my tablet?

[xiao xiao]

I am logged in as can be seen but when I try to login with the same usename and password on my tablet I get the message 'no such username exists'

As can plainly be seen I do exist.

whn registering I had a mix up with my username which Kizzie kindly rectified for me - is this still a continuation of that mess. I thought it was settld.

How can a message 'username does not exist' appear when I plainly do exist?

You registered on OOTS with the username xiao-xiao (with the hyphen)
It looks like you may have subsequently changed your profile name to xiao xiao (without the hyphen)
You can only log in with the original username. See if that fixes the problem.
