755 is fine for folders 644 is fine for files. The 7dana-Xred file loaded fine when called directly, so it looks like it is placed in your site properly.
The next step would be to set it as your default theme and ensure that it is selected in the 'selectable themes' list in System->Preferences. Also, turn on PHP debugging. Once all that is done, reply back and I'll look at the results on your site.
