How to get (old intel) BTT back on Apple silicon MacOS?

Hi, I registered BTT sometime ago on my old intel macbook and switched to m2 macbook and it still works after I copied the old btt and license to my m2 macbook.
Until recently, Without deleting the app, the app magically disappeared from my system suddenly.
I'm not sure what happened. The app shouldn't be able to delete itself right?
I forget with which email address or what account I registered it with. Is there any way to get the old version back? I still have the old intel macbook but already reinstalled the system and haven't been using it for a long time.

it can‘t delete itself :wink:

You can get old versions here: Index of /releases

However be careful when running versions that are not optimized for Apple Silicon, they can cause serious performance issues

Hi, Mr admin
I found the license file, but the app in the link are not supported already. the downgrade button does not work.
can this provide any information?
