Hi,

You did not mentiond which version you use. Anyway, this is a common problem. If you are talking about the soundpool in the Magix Music Maker you got two choice accoriding to my experience.

1. If from a Soundpool style example Hiphop, when you try to drag and drop any audio of instrument suppose drum, bass etc you get this error, you can do one thing, in the Program file there will be Magix Music Maker folder, go to that locate Basic_15 or Basic_16 whatever your version could be and then located the style giving you error. Copy that entire folder some where such as My music, resave it.

You got option to save once again in the Program folder from where you had copied it will replace with new one.

Note: ONLY IF YOU GOT the installation CD/DVD otherwise do not mess with original folder please.

If you do not got any installation CD/DVD then use Addstyle button and browse to the re-saved folder in My Music it should work fine.

Other than above, when Magix Music Maker is open, click on computer "Y" key it will open Program settings of General tab, look at right side below you will find Reset soundpool click it follow guidance and click ok and leave. In this case you will have to use Addstyle to add soundpool again.
