Install & enable additional file systems problem

I'm facing more issues with getting LMS to work with my local USB drive.
I had to move some cabling around so I stopped LMS, moved the cables, restarted LMS & got the old problem of the mounted disk not being accessible.
In desperation, I figured that removing the additional file systems option might be worth a try as I could always reinstall it.

I now get:
[ INFO ] Downloading additional file systems support...
There was a error downloading ntfs-3g.tcz.
Retrying extension ntfs-3g.tcz...in 5 seconds.

I've tried with LMS running & stopped. Ditto for Samba. PC & Pi have been rebooted.
I'm not techy so haven't been working at command line level, just LMS options.
Please can anyone explain how I get it back?
Thanks
