Rated 3 out of 5 stars

Unfortunately, update v1.0.3 doesn't seem to work any better than its precedents on my system (Win7 + Thunderbird 31.3.0 + Lightning 3.3.1)!

Nonetheless, i've not given up hope yet...

Edit: As suggested is tried unsuscribing and re-suscribing, but to no avail (other than getting my calendar to work for one single day)!

This review is for a previous version of the add-on (1.0.3).  This user has a previous review of this add-on.

Could you try unsubscribing and re-subscribing? Please also check the support forum.
