    I was able to resolve this without assistance from Customer Service, who replied to my issue report with a notification that it had been reported, after which they marked my issue as "solved".

    I manually launched the MTGALauncher.exe application from "C:\Program Files\Wizards of the Coast\MTGA\MTGALauncher"; the program downloaded a required update, after which I was able to log in successfully.
