YAY! i worked out how to fix it:
Type ".where" in game, note down the X/Y co-ords
LEAVE UO RUNNING AND PLAYER NOT MOVING
In UOAM "Go to location" and enter the 2 numbers
Click "Latitude/Longitude"
Note down all the entries
In UO menu of UOAM (UOAM must not be topmost) click "Calibrate" and enter the values obtained above
Bingo! It works!
im confused...mine stopped yesterday without installing anything new and despite calibrating it it still wont track me
