Have you stepped through your code and verified you are making the call to SetAddinInfoEx?
If so, are you sure you are in the part environment when you look at the Edge UI and not in synchronous part?
Right click in the part window and on the shortcut menu, choose "transition to ordered" (not sure of the exact text). You can look at the app caption when in part to see if it is "sync" or "ordered" as there is text added to the caption. I'm betting you are in sync part when you look at the UI and that is a different environment. Changing to ordered will reveal your tab.
If your commands are the same for ordered and sync part, add to your if statement "CATID_DMPart". DM is "sync" (the name changed but I kept the CATIDs as is to protect the innocent.
