DaniWeb IT Discussion Community - Doesn't open for file input successfully.... why?

**I know the code looks big, but it's a very small isolated section at the bottom (starting at line 164) that's giving me the problem.**

When this program is run, when I try to open the file I just appended some text to, it doesn't open... can anyone spot why? Thanks....

p.s. Yes this is a program I made after following a tutorial, incase you're wondering.
