userman database not accessable

I am having a problem with setting up userman
i made a hotspot and and made a username and also made a radius, but when i try to go to the userman page and login it says “invalid username or password”, so i tried adding a user through terminal and this is the error:

[admin@MikroTik] /tool user-manager customer> add login="mtadmin" password="mtadmin" permissions=owner
failure: database is not acceseble, yet

and when i tried to print the router’s details it did the same thing:

[admin@MikroTik] /tool user-manager router> print
Flags: X - disabled 
database is not acceseble, yet

i searched online with no luck… there is nothing about the database???
my version is 6.23

Never mind.. took forever for post approval, problem was database was not setup
added new database by going to

tools/user-manager/database/set "database.db"
