MInimServer doesn't restart

[davidp]

Initially installed MS alongside Twonky but soon disabled Twonky - MS running fine.
Check file system required a server reboot on QNAP TS-412.
Minim Server now will not launch but gives error Safari cannot open page XXX.168.0.9:9790 because Safari can't connect to server "XXX.168.0.9".
Tried all startup troubleshooting tips but same error message every time. Twonky sever is working fine on another port and clearly Safari can connect to the server. Minim Watch icon grey.
Any suggestions to get going again please as I really, really liked MS when it was running.
