i can still use my magix 14 because it installed on my computer but once i uninstall it im screwd inless someway i can recover it thru the company maybe??
Your version is little bit old, the only possibility is, if you have purchased download version then you must got payment details amount, date, place of purchase and in the confirmation e-mail you should have serial number or key.
Copy those information and contact Magix support and tell them you problem may be they will give you download link.
In case of Box version it will be difficult in both cases contact Magix support at earliest.
Thank you
PS* don't you have installation file, or you did not keep backup? that mght be helpful to re-install.
