Master password

I forgot the master password. How i can reset this?
I run eM Client on win 8.1 e i have the eM license registered and activated with IceWarp Desktop Client

Hello, unfortunately it is not possible to reset the master password, if you lost this password, you can only setup a new database by renaming or removing the old database from the local user/AppData/Roaming folder. Next application startup should automatically force a new database to be created.
