viAdmin locked out in a lab environment

Hi, I'm using version 8 and I'm trying to authenticate with System user. I don't know the viadmin password in my lab anymore so I can't access anything and it is now locked out because of too many password attempts. I have access to the database and I can see the account in the DialogUser table but the password is encrypted. Is there any way I can access my lab? Also, can I update the DialogUser table to have 0 BadPasswordAttempts so that I can try some more passwords that it might be or will this corrupt the database?
