This is an issue in the version checking code of Memento and appears to happen in DW CS5+
It is incorrectly checking the versions of extensions you have installed and sending erroneous update messages. WE are looking into correcting the problem so that the update announcements are only sent to the intended groups, we apologize for the confusion.
The update notice for HTML Editor 3.0.2 should only show if you have purchased HTML Editor version 3.
The update notice for SecurityAssist 2.0.1 should only show if you have purchased Security Assist 2
In your order history, I see you have HTML Editor 2 and Security Assist 1. you would need to purchase upgrades to HTML Editor 3 and Security Assist 2 to get the updated HTML Editor 3.0.2 and SecurityAssist 2.0.1 versions.
