Problem solved, thanks everyone for helping! I have an error with permissions set up. my error report: 2012-05-01 21:15:24 [WARNING] Server permissions file permissions.yml is not valid YAML: while scanning for the next token found character '\t' that cannot start any token in "<reader>", line 3, column 1: group: Admin ^ my permissions file
\t means Tab. You used a tabs to do your indenting. You have to use spaces. I'd list out the line numbers you need to fix, but its almost every single line. If your using notepad++, you can go under Settings > Preferences > Language Menu/Tab Settings. Put a check mark in Replace by space. That way any time you press tab, it will use spaces instead. To fix an existing file, under Edit > Blank Operations > TAB to Space.
