mysql not working but very odd

Ok, I had php installed on a server with mysql module and I just copied all the files over to a new machine. It didn't work. I tried reinstalling and all, still same issue. I ran php -I output and it seems to be all ok, this is part of the output: mysql MySQL Support => enabled Active Persistent Links => 0 Active Links => 0 Client API version => 5.0.37 Directive => Local Value => Master Value mysql.allow_persistent => On => On mysql.connect_timeout => 60 => 60 mysql.default_host => localhost => localhost mysql.default_password => no value => no value mysql.default_port => 3306 => 3306 mysql.default_socket => no value => no value mysql.default_user => no value => no value mysql.max_links => Unlimited => Unlimited mysql.max_persistent => Unlimited => Unlimited mysql.trace_mode => Off => Off Now, when I try to load a page I get an error: This page cannot be displayed due to an internal error. You can provide the following information to the administrators of this site to help them solve the problem: Error: mysql extension not loaded You can see the error in http://www.unionlatina.org/ Any ideas what's going on? I tried putting the files in c:\windows\system32 and same thing, I can't think of anything else. I've installed, reinstalled, restarted, removed, downgraded, upgraded, copy the exact files. nothing always the same error.
