Hi Ian,
I apologize sincerely for the issues you've seen during your free trial. Sadly, you joined us at a difficult time and I understand that you've had a very frustrating experience, which is never a good way to start out with a tool. I've responded to the help ticket you sent in, but I wanted to follow up here to make sure that you know that your trial period has been extended for another month.
Both the Rank Tracker and Keyword Difficulty tools should be working again, apart from an issue with the AdWords data on the Keyword Difficulty tool. Unfortunately, Google is currently not allowing us to provide that data, but we are working on a solution to provide that information in the future.
To all of the other users that wrote in, thanks for sharing your good experiences with Ian and I apologize again for the difficulties of the past few weeks. We are working on making things better so it is easier for us to recover from these types of machine failures in the future and we truly appreciate your support.
If any user is still experiencing any issues with their campaigns or has any questions about the issues we've had recently, please feel free to write into us at help@seomoz.org.
Thanks again,
Chiaryn
