Blank screen after uploading files.

Hello RaGEZONE users.
Ive got a problem with my registerpage.

Ive downloaded a Registerpage (Wizkidv2) and put it in the xammp>htcdocs folder.
I look at localhost and it works fine !
So, I started to upload my .php file with Filezilla on my ftp account.
Everything went fine, I've uploaded it etc..
So, Ive uploaded it and when I go to the site where its located, There comes a white screen o_o ?
So, When I got to the page where its located there comes a white screen. No registerpage...

I use Freehostia to upload my files.
Ive got a Ftp account and so on..
What can my problem be ?

Already thanks !
Elec.

Btw. I use xampp :)
