Assuming you mean using the Magix Xtreme Print Studio, this is no longer available/installed.
Are you using paper labels or printable discs ?
If using printable discs then you should have software that came with the printer for doing this, in my case I have Epson Print CD, which prints the disc and the case inserts.
If using high quality self adhesive paper labels, there are many third party CD/DVD label printing programs available, you may have one that came with your printer.
If so, run it. I still have it with older programs and Sound Forge Audio Cleaning Lab 4 - the most recent. This is actually Xara Xtreme.
The templates are .XAR which is for Xara. If you have any of these files, make a copy somewhere that the uninstaller for Magix programs won't touch. If you happen to have a copy of Xara Designer Pro X or Xara Photo & Graphics Designer, you can open the XAR files in that.
Otherwise, you have to use something else, as John EB has pointed out.
