So a few users were reporting crashes with the initial version of the Mira package. Specifically, there was one crash coming when opening the mira.frame helpfile, caused by some bad interaction with fpic. Another crash was related to WiFi negotiation for certain configuration-platform complications. Both should be fixed now.
An updated version of the Mira package is now live on the Mira product page. All you need to do to install the new version is download the Mira package and replace the old package.
Thanks everyone for the thorough and very helpful bug reports! Keep them coming as they pop up (though hopefully with less frequency now) and I'll keep the fixes coming as fast as I can.
