Which CMS are you using ? What have you tried ? Are you getting any errors ?

I am using joomla...Tried to get assistance though my hosting company (Hostgator) they referred me to you...I tried to install it through my hostgator control panel, I think it is still there...This is the error I am getting--- Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@grannysay.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Please make sure all the files and folders in freichat including freichat directory have 0755 permissions

I tried that and now this is the message i am getting....Error: 404 - Category not found.....

Do you get this error while entering the url http://your_site/freichat ?

Make sure you have not renamed the folder freichat .

Yes that is when i get the message...Please help me...

Then you either have uploaded the folder in the correct location or have you renamed the folder ?
