Hi Brenda,
Indeed these are different service packs for Adagio Payables 8.0A, and as such will have different passwords. As Adagio service pack passwords are not automatically emailed, perhaps you have an older email with an old password.
Your best bet is to contact your Softrak business partner, who has access to the latest service pack passwords, or to contact Softrak Customer Service at info@softrak.com.
