There were no other files besides the 'old' one. (I double checked w/ Find).
MySQLi works fine (just turned it on for kicks), the problem is...every single database function I have in there (from the OS stuff like forums to my stuff) is in MySQL. It would be a hassle to change it simply because the php_mysql.dll doesn't work.
Yes, it uses the right php.ini file. (C:\Windows\PHP.ini)
