Are you using a Dutch version of ME?
If so, iirc there was some ME unofficial service pack that got removed. I may still have it somewhere.
And I don't have an actual list of ME updates, but I did download all available ME updates with Windows Update years ago. Same story, I should still have those and I actually uploaded them and put a link to this thread (I suppose the upload is long gone now though).
Edit: All ME SP's I tried were for the English version of ME though. It would still install but it turned my ME into a Dutch/English hybrid. And I also remember I never just installed the entire thing, but only selected some of the options. But it's been so long since I last used it, I'd need to check my old database harddrive to see what it contains (the rig I used was dismantled a while ago but I never formatted the drives).
