I can use some help with this same issue - I got the file from Drop Box, I added it originally to users> username> elation> common > Personalities > User. (I am using a Mac OSX 10.7.3)
When I did this I could load the Intimidator Spot LED 150, but I had the exact same issue with regard to the lights not reacting to the position - it was very shaky and would not go where I pointed them.
I then did what was in the post as per on page 30 of the manual - I added it to Users > Username> Common > Factory (had to move that folder from Personalities along with the user file and then I deleted the Personalities folder) - when I did this the fixture was not there.
I have no idea what I am doing wrong but now I have (3) Folders called "Factory".
One is under
Users > Username > Elation > Factory
The second is under
User > Username > Elation > Common > Factory
The Third is under
User > Username > Elation > Common > Personalities > Factory
I hope this makes sense but I am going kinda of nuts trying to get this to work right
