I get an error when trying to play any of my tracks. I can load them but when I press play, an erro message pops up. This started very recently. I have done nothing to my compute. I run on windows XP on a Dell PC
Anyway, the best solution to your problem, re install the software ONLY if you got installation CD/DVD etc.
If you could re install
first back up all your projects or important files, even saved presets in Music Maker.
un install software
clear browser cookies and history, delete all left behind folder in Program, Appplication data or in Program data
turn off computer.
After few minutes turn on computer and re start then please re-install your software. Note, do not run other software, email, messenger, internet when you use Music Maker.
Hope this will solve your problem. In case of any other technical help you better contact Magix support.
