Full feed won’t show

Hi, I’m not extremely tech-savvy so I was hoping someone could help me figure out what I’m doing wrong. I want my feed to show full content but eventhough I’m not using the more tag, the setting in WordPress is checked to Full Feed and also in Feedburner and my feed is pointed to my RSS2 file I still have only a summary showing up.

I tried a fix suggested in this thread but now my rss2 file seems to be all messed up even though I switched it back to what it was originally ??

Can anyone please help?
