Since it seems your problem persists
Here the checklist
1st
Which browser are you using (supported are Edge, Chrome and Firefox)?
Did you tried another browser (and had the same issue at 95% or different)?
2nd
Are your browsers fully updated?
Do you use some add-on which might prevent something (script or popup blocker etc)?
3rd
Try to start a new account (just for testing or having fun at the lower levels;-).
If you can logon with this account your problems are related to your original account (db error).
4th
Running browser in debug mode might give you additional hints.
Happy testing
and
good luck
Jack;-)
