I got my new flyfishing setup. It's a 9'ft

I went to cast it out, and it went out only about 5ft or so. The current took the line right after I pulled it off the reel. What's wrong??
I already ordered the flyfishing video

This will help for sure. I also am contacting
a guide in my area, but I just wanted to
know what's going on.....
Thanks
