What do I do if I forgot my password?

If you have forgotten your login or password, please delete the uzytkownicy.dat file from
Data directory where the program is installed.

It may happen that the file will be hidden. If you want to have access to hidden files, just go to My Computer and select Folder Options from the Tools menu.
Now all you have to do is go to the View tab, and then find and check the Show hidden files and folders option.
