Answer 1

Usually this happens because there is already another Fuse instance running, with the same current directory. If you started Fuse in a way that doesn't create a console, it's not difficult to forget that you did so, and try to start it again. Fuse is designed to work this way -- it's not an error to try to start multiple instances with the same working directory: this is often done for redundancy. But it can be hard to spot if you've done it by accident. Use "jps" or something to see if another JVM is running.

There are other potential causes of this problem that can be explored, but it's worth ruling out the simple explanations first.
