Instalation Question

[محروم.كوم]

I am installing my first vbulletin forum and I need some help. First I purchased the owned licence then I put the url in the licence then I downloaded version 3.8.3 then I extracted the files. After that I edited off the .new from config.php.new and uploaded tools.php to the admin folder. after I filled in databasename, tecnicalemail, master server, the username and password. Then I used filezilla to upload everything inside insidethe upload folder to my server. I finally got to the part were you enter the http url with the install/install.php ending but the web browser just took me to the blank page were I want my forum, but there was no vbulletin installer. Can someone please help me, I'm not sure what I should do? __DEFINE_LIKE_SHARE__
