Help! reinstall php script

I am having serious issues with my software. I am currently using phpfox program but it wont let me install the videomod plugin and the musicmod pluggin because my upload limit is not set to 100M. I contact dreamhost to see if they could do this upload for me they said they cant because if they do this chage on my server it would affect everyone on my server. They said that instead i should reinstall my phpscript and customize it the way i want!! i have no idea how to do this at all. Phpfox are saying that there is nothing they can do about this either so i am on my own. Please i need help instantly please. Any help is welcome.

Please don’t double post. It’s extremely rude. See post here for replies.
