So frustrated when I look at your name: Admin, no you are wrong.
I registered account at open subtitles.org. not this forum, and this account let me login this exactly forum. So Mr Admin do you even know what are you typing?
As the Smallbrother said you need to create a separate account for both of them.
The account you registered on the site .org/.com doesn't work on the forum.
You must have been mistaken.
Or maybe I don't know what I'm typing either... hummmm
By the way, i search on .org for user justforpt : User was not found!
Try again and register here :
