For Andrei urgent

I presume that you can use 1.80 or 1.90. So follow the next steps if it's true:
1. Connect to your database and execute the following command

UPDATE [Nop_Setting]
SET [Value] = N''
WHERE [name] = N'Security.AdminAreaAllowedIP'
GO

2. Restart your application (save web.config file without any changes)

well, just in the folder named Nop Commerce inside encounter a file type. txt named licence and and can read this
