Serious computer help! Answer please.?

I have a 2008 compaq laptop, we have 3 different user accounts on it. the administer account says "the user profile service failed the logon, user profile cannot be loaded" ; it is windows vista & you have to create recovery disks when you first access the computer, i didnt know you had to do that; so now we dont have a recovery disk. can anyone tell me what is going on , or what i can do to fix it ?
