Piwik download issue

When downloading the zip file, it is only downloading with the total size of about 2.2Mb, while the piwik site estimates it to be 8.6Mb. Is there a hosting issue or am I downloading it incorrectly?

Nevermind. It was a proxy issue.

I installed on my server Pivik. The installation program displays an error: http://movies-news-mob.com/analytics/index.php?action=systemCheck. I rebooted the program 3 times but the result is negative. Help please
