How do I resolve a 'Too Many Actvations' problem ???

I have over 100 purchased DRM eBooks I cannot read because Adobe Digital Editions refuses to 'Authorize' my device (a Kobo Aura One). The problem has arisen because the device has had to be reset 3 times in 10 days owing to a software glitch.

Somebody please help, I'm losing the will to live, LOL.
