Installation Problem - Fatal Error

[Macksimise]

I am attempting to install SugarCRM 4.5 and I have got through the setup pages, until the system reads the performsetup.php file, when I get the following error:

Fatal error: main() [function.require]: Failed opening required 'modules/Schedulers/Scheduler.php' (include_path='.:/usr/local/lib/php') in /homepages/25/d124217500/htdocs/Sales-Insight/SugarSuite/install/performSetup.php on line 40

As newbie to the programme and to web development I would be most grateful for any assistance.

Thanks
Iain

Problem now sorted! I ftp'd the files to my server and not all of them copied. Basic newbie error!
