FLV files not responding

Here’s the problem. My flv files won’t run if I move the folder where I have all the contents. How do I fix this problem so that I can run the flv’s no matter where the folder is?
I know this isn’t exactly an actionscript problem since I imported them directly to the library and from there to the stage, but I desperatly need some help on this matter.

Thanks in advance for any help!
