Won't update Rated 1 out of 5 stars

restarted after the update and I was notified the old version was incompatible. Checked, and found this version. The update hung for 20 minutes. When checking the add-on tab, it keeps saying there's a new version, no matter how many times I update and restart.

This review is for a previous version of the add-on (1.6).  This user has a previous review of this add-on.

Please do not use the reviews as a support forum! Try uninstalling Lightning fully and reinstalling again, given you have been using since at least 1.0b7, there may have been an issue with the Mozilla Addons Manager that corrupts parts of the addon database. Also, make sure you are using Thunderbird 14 with Lightning 1.6.
