Hope this is in the right section. I installed the free trial of Mark Studio 1 by Markbass only to find that every time I start up GarageBand it says, "An error occurred with Audio Unit plugin Mark Studio 1, the software may need updating." Okay... well I guess I should uninstall the software or update it. However, the software is up to date (I confirmed) so I have to uninstall. The weird thing is that there is no visible trace of the downloaded/installed file anywhere other than the downloads folder and that's just for the installer. I can't find a plugins folder or anything to get rid of this nuisance... any help? If this were Logic I am supposed to find the file in Library>Audio>Plug-Ins>Components but the file is not there. EDIT: There are two "Libary...Component" paths on Mac OS X 10.6, some of you may have already known this but one is User and one is HD. The file was under the User path... feel free to delete thread if no one will benefit from this any longer.
