I apologize for the delay, everybody. I believe we are close to a resolution, and should have another update soon.
This issue should be resolved at this time. Please attempt to activate the LastPass Premium again, and let us know if any errors should reappear.
Ash, I will send you a PM about this with some screenshots. The "subscription key" link now appears on the Logmein page. When I click on it, it opens up Lastpass and says "This offer couldn't be redeemed. You already have an active LastPass Premium subscription." I definitely do not because it shows in my settings as a free one, and it even prompts me to purchase Premium when I am in my account.
