Welcome to the Magix Sound Forge users forum @44Liquormart . Just so you know, this is a user-to-user forum and no one here is a Magix employee, including the moderators.

Sorry you are having problems, 'Add-ons' are usually associated with browsers and email client software. If you are referring to 'plug-ins', specifically which ones and where did they come from?

Otherwise you need to state more information, read the sticky at the top of the main SF forum page.
