I initially thought it must've been the files I was using weren't in the correct format, type, etc. However, I'm just going straight off of the "Testing the Video Multiplexer GP Tool" word document that the tutorial came with and am using the files in there. The tool is still not working.
Anybody else dealing with this? Do I just have the wrong version or perhaps I stored the GP tools files in the wrong location. Thank you for any and all help.
