I have the software I've registered in the past and I formatted my computer now. When I installed the same key it told me it's being used. What can I do?
You can download a new version of the application from the official website and then use the technical support in order to obtain a new serial key for your program. If you have old details, the company will verify you then blacklist the old one and issue a new key that you can use. You contact the company using their official support page.
