Have you installed any other addons since this started happening? Did you install the new Flight Logger (3.0.7) over the top of the old one (3.0.6) without uninstalling it first? If so, uninstall the flight logger completely and then try re-installing it? I believe that this is a problem with an Addon and not FSUIPC. You may have installed an unregistered addon that is trying to use FSUIPC that is what is causing the problem. Many freeware addons can register their products freely with Pete Dowson but some choose not to, I think this is what has happened. Think back carefully to when the problem started happening and look at Aircraft, Scenery or other addons such as panels or guages that you may have installed and see if uninstalling them cures the problem. I would starty by uninstalling Flight Logger completely and re-installing the new version from scratch, you may find this helps.
