Unsigned Developer error Mac Catalina in DAW

I am not able to use MIDI Guitar 2 in my DAW – have tried both Reaper and Logic, getting a recurrent error box which is not fun. Also I have somehow misplaced my license although I still have my email receipt after I purchased the app. I sent in this request through the online form but am still waiting for a response.

Make sure you have the 10.15+ version installed - it is signed. Download – Jam Origin and overwrite the old audio unit (MIDI Guitat 2.component)

I need my license file can you send me it?
