This might be a stupid question, but here goes...

I run the latest build of JD, have a MacBook Pro, an airport extreme, with an external HDD attached. I have all my media files on the external drive, but I can't seem to download directly from any links to the network drive.
The download speed is very slow, and JD always freezes, and then crashes.
The partial downloads will not resume, when I restart JD.
I have mapped my download folder to /Volumes/2TB-1/Jdownloader

2TB-1 being the name of my network drive...

Any ideas ??
