Read Only (after Permission Denied)

Recently, I posted a thread called Permission Denied because that was the error each time I opened the index. Please read my problem here http://www.choiceofgames.com/forum/discussion/1290/permission-denied/#Item_2 so that I don’t have to repeat myself. Anyway, I think I found what’s causing the problem; after right clicking on the main folder that contains all the documents, I noticed that the “Read Only” box was filled. So I unchecked it, hit apply, and then okay, and then I closed it down. But when I opened the properties again the box was re-checked. I tryed checking and then unchecking one of the other boxes to see if it worked and it did, so it’s only the read only setting that’s being affected. Can anyone please help me out with this?
