MG3 Beta version stuck screen

I changed my audio buffer to 64 and now I cannot bypass or change it back to 256. I am unable to re-install MG3 as it seems to be no longer downloadable so I cannot continue to trial it which is sad.

Is there any way to either re-install MG3 from a downloadable link? or bypass the locked screen to change back to 256?

Many thanks.

Please try changing the buffer size in the audio interface dialog window. Next startup MG3 will recognize the changed buffer size.
However MG3 runs well on 64 samples > it might be a hardware issue with your computer that it freezes.
