cannot logon anymore and reset password doesn't help

[LordISP]

Guys I need your much appreciated help

I kept the system for a longer time alone and must now do an IP change nut I cannot log on to the admin panel anymore, I simply forgot the password. When I do a password reset procedure and enter the new received password I get again a invalid user/password combination.

Any idea whats wrong or how I may fix this. I can root access the server and have also god permissions to the mysql database.

Thanks for any feedback on this one!!

Cheers
