Near the bottom of the thread you'll find a link to my 16km ATM.
Rollback SH3Cmdr.
Disable your original 16km ATM
Unzip my 16km ATM & Copy into JSGME's mod folder.
Enable Via JSGME
Launch SH3Cmdr
Enjoy.
This should fix your woes.
Edit - I must add that this is nothing special just my copy of GWX's 16km ATM
