Jamkazam app crashes on startup

[iVersonic]

new to jamkazam and wanting to give it a try but after signing up > downloading the app it crashed immediately after start up. i've read this thread but other than creating a new user and making that user an admin, i am still not seeing a resolve. 

here are my specs.
MacOS High Sierra 10.130.6
Processor: 3.2 GHz Intel Xeon W

i tried changing the sound preferences to use the Mac interal mic and output but still no luck. can't even launch the app to change any preferences.

its strange as it doesn't ask me where to install the software (drive) and all the usual things when installing an app so i feel like it wasn't fully downloaded or installed correctly even though it says it was finished.
