Hello! I'm having problems with multiple programs (Word, and two converter programs) whenever I am in the browse window and navigate to My Videos folder or any subfolders. Basically as soon as I enter one of these folders the program says it has stopped working.

I've seen this problem on here three other times:

(Tried both solutions.)

(Tried the first solution, the second link is dead.)

Any help is much appreciated!
