administrator no password

Ok, yesterday i had problems with hiding the administrator account no my computer (vista), i finaly pulled it off but now everytime i need administrator's acces i can't enter a password or just press ok. I'm 100% I didn't save a password for the administrator. The only other thing is the logo of the acer fingerprint reader also pops up, but when i scan my fingerpringt it gives the green cirkle (approved) and then does nothing. The only thing i can do then is press cancel.

Go into BIOS and check if there is a Password enabled there and if so disable it.... should let you in then.

lol that fixed it, tyvm elder

this can be closed now
