Conversion of .SWF File

So, for the fourth day in a row I have tried to convert my .swf video file. I have contacted a friend from high school who is now a computer programer/computer specialist. He recommended the program Twain. It is the conversion program, that was free. Well, it worked or so I thought! It just recorded what I had done and then put up a screen that showed the conversion. NO VIDEO! I was so upset. I then saw that Dr. Pierce said to use ZamZar. When I tried this program it said that the site did not currently support .swf files. So what is a girl to do? For now I am clueless! :( I guess this is one of those learning experience, but for some reason...I am not liking it!
