The thread you referenced locked because it went 60 days with no activity. In this situation, we would recommend creating a new thread and referencing the previous thread as desired. We implemented this locking feature a couple months ago for a variety of reasons, most notably:
- Customers were not getting supported nearly as well when posting follow-on questions to existing threads compared to when they created a new thread
- Some people would keep posting follow-on questions on the same thread, even when the questions had nothing to do with the original post
In the next few months, you will see us adding features that will make creating a new thread on a "related question" easier (including automatic cross-linking) and additional locking features to ensure every thread is properly addressed and closed out.
