From the Help menu, choose Disabled Items and see if the add-in is listed
there. If so, enable it.

For quite some time I had an Add-In working fine, now it is gone...

It is still listed in the Tools manu and checked, but it does not open!


What do I do wrong? When looking for it, I tried to open the file, but
nothing happend.
