Hi,please anybody help me,i am trying to make a communication area for people from my summercamp .I have installed all the modules via administration console,but none of them is working.

-If you try for example to use forum,chat,videos or anything else,it writes you webpage not found.

I am hosting this site by my own on my windows server 2008R2 on adress: http://195.47.47.50/boonex/

I havent installed and configured cron jobs,because i dont know how to do it,but i have read,that it is only for mass mail sending and so the problem do not seems to be there.
Permission is allright,Apache is working,PHP,MySQL,all except the modules.
Please feel free to visit the page and write what is wrong.
