Change admin password in New server after hacking

[binuj01]

Hi,
 My web site got hacked, hence I have installed the new 4images 1.72 version in a new server. The installation went well and I was able to login with the new username & pasword I created. After that, I dumped the old Sql database and the database got updated. But now I cant login with the new username & password I ceated, but I can login with the old username & password . I presume that the old username& password got dumped when I restored the old data. I looked at the config.php file, which has BUT the new username & password only.
Where could Have I gone wrong.
An urgent help is requested.
Thanks
Binu

nothing went wrong...edit your user account and change the password...
P.S. IMO this questiong is a little bit strange

this question is really a little bit strange.

just a short advise.
if you got hacked, change all passwords,
not just the pass from your 4images useraccount,
also the SQL username/pass, and if necessary also the ftp pass.

Very good point, IcEcReaM.
Only one thing to add: delete any "suspicious" files, the files that are not from 4images package and these which you didnt upload.
