Unfortuantely, if you deleted the account or if you no longer remember its password, you can't restore it to your computer. If you can't access PSBA Money Manager anymore, I suggest you uninstall it (Control Panel > Uninstall a program), run a registry cleaner from Software Informer database to make sure that there are no leftover registry keys in your system and install it again. In this way you will reset the software and you will be able to create a new account. For further information, I suggest you contact the developer.
