Database location for plugin files

I moved my WordPress site to a new location (domain name and database), but it seems like the Soundy Audio Playlist is still referencing file/folder locations from my old website location (such as the play/pause button image files). I tried uninstalling and reinstalling the plugin, but my old settings were saved, and the bugs still exist. Does the plugin store data in the wordpress database, and if so, where can I find that to wipe it clean? Thanks.
