After you edit the flash.txt your logo, slogan or phrases are not showing up or only parts are showing up.
Full Lines Are Missing:
You may have deleted the "logo=" or the "&slogan=" or other code in front of the phrases. Best solution is to download the template again and start with a fresh flash.txt.
Parts of Lines are Missing:
The most common cause of parts of the lines missing is the use of the ampersand (&). You can not have a linked text file that uses the & sign. If you need an & sign included in the animation you will need to use %26 in place of the & sign.
