program to check roboform logins

does anybody know of a program to check my roboform logins to see if they still work. i use roboform and have accumulated 800 logins, but i dont use them all they just kept growing when i backed up roboform data folder where the logins are stored without going through them first.

does anybody know a program to check if the logins are still valid, obviously its not practical to check login data for all of them so a simple check to see if the sites still exist would be enough.
