I've installed and tested then retested the software with in all kind of situations and it responded correctly. I must believe that the error you're receiving is actually related to the a wrong password, because once you type the password, the application will allow access to the created databases.
One simple bug, if I can name it this way, that I encountered was when I entered the password. For some reason, it appears that when you type the password in a fast way, it displays a password error. I've typed only one character at the time and it worked normally. Try this and double check the password you enter.
