After three posts you should be able to PM... Try Gábor again... But I see that, although you joined two years ago, you have only posted here recently. I assume you have been using the SCF PluginStore's dialog on various SketchUp versions and computers. Have you downloaded Plugins from SCF ? Your original user-id etc might have lapsed as the servers were changed about the time you registered. So you might have lost your earlier user-id for the SCF PluginStore ? When you use the PluginStore, it submits your currently installed/downloaded for that version and computer to the server and it's stored with your account details, against your-id. Obviously your replaced computer no longer has your locally-stored user-details. But there might be something stored against your user-id server-side. Gábor can advise...
