Rebranding audio button creator software

I have an application branded with a name that no longer exists.
I need it rebranded with my company name. Updated to point to my website

Hey, do you have the application source code? What language is it coded in?
Thanks.

No sadly I don't have the source code and the website I bought the MRR from does not exist anymore so I can't get any info. There are a few free ones out there but if this one could be rebranded with the ability to update it would be very useful
