I keep receiving this Error message everytime I go to open Soundtrack Pro 3.

Error Message Reads "


Cannot remove an observer <LoopMetersModule 0x1d46a1f0> for the key path "Meter Jack Order" from <NSUserDefaults 0x109a9e0> because it is not registered as an observer."


Attached is the error message and my computer specs.


How can I fix this problem?

    The images do not display.


    Did you install STP from the original disks or did you migrate it from an older computer?


    If you migrated it, download Digital Rebellion's FCS Remover (free) and use it to delete STP from the computer then reinstll STP and do the updates.


    Good luck,

    I installed it from the original discs. I went away for about a week and came home and tried to open it and got this message. I've never had a problem before until about 2 weeks ago.


    Here's the image of the error:

    Just got this same message. Happens about 4 times in a row when opening a new audio file. I haven't used the app in over a year. I suppose all the MacOS X updates in between have hosed something up.


    The last thing it did was suddenly go silent in the middle of playing a track. The meters went dead as well. Time to move on I suppose.
