error Message installing webinstall

Well I uploaded it on the host then I got this
We are sorry but the installer was unable to download the installation package details from the Simple Machines website. You may download the packages manually by using the SMF Download page.

Click here to try this step again.
So what am i suppose to do I am confused.

if it doesn't work, do as it says, "download the packages manually by using the SMF Download page."
