There is no automated uninstallation script. To manually uninstall, edit the file start_app.sh in the root (share) directory of your NMT (also known as /opt/sybhttpd/localhost.drives/HARD_DISK) and remove the line:
cd /opt/sybhttpd/localhost.drives/HARD_DISK/.ctorrent/ && ./dctcs_boot.sh
Then remove the directory .ctorrent which can also be found in your root (share) directory. That's all.
