I have read and still reading...I even tried to do it ftp wise and it say

Unknown Archive Type

On a remote hosting environment, if you do not have access to this file you will need to contact your host helpdesk and have them make any changes needed for you to increase the ‘upload_max_filesize’ php parameter. Actually, even if you do have access and can modify it, better be safe and open a ticket with your helpdesk as additional steps might be needed from their end (e.g., perhaps server restart is needed depending on hosting package).

I talked to my host and its on 2 and they will not change it. So what I do now?
