Help me with third party tools plz!

Hello I am in love with Knytt Stories and I love making levels but I have had some trouble with the 3rd party tool KS manager. Whenever I run it it says, "Multimedia Fusion Stand Alone Application has stopped working." It has the option check online for solutions (which of course NEVER works,) and close program. I am at a loss, I have used it before on other computers it would really improve a level I am working on. If anyone knows this problem please help me out. 

Try redownloading it and replacing the Manager you have now. And make sure you don't have the Knytt Stories Manager somewhere with a really long path thing (like C:\Users\Blah\Files\Documents\Games\Nifflas\Knytt Stories\3rd Party Tools\KSManager\. Longer, even). I think some people have had problems with it because of that.
