I have had that happen to me with a providers disk several times (same provider, different clients). I forget the exact fix, but I believe it was something to do with removing the keys that I found with that providers name. Then I believe I had to load a higher version of explorer to get it to repair itself. If it was my system, I would go awhile until I couldn't stand it anymore thinking it wasn't right and I would reload..............
Anyone else like that?
