So what I did? I installed Oblivion in the same path I had it installed in the old computer (c:\games\TES4 Oblivion)
After I installed it, I copied/replaced the entire content of my old Oblivion folder to the new one, including all mods, OBMM, etc, etc, etc
Then I copied/replaced the entire content of the "documents\my game\Oblivion" folder to the new computer (on the same place the new Oblivion installation had created the folder)
However, when I start OBMM, no mod is selected. Where can I find OBMM settings, so it will behave JUST as if I was still at the old computer? (same mods already installed, etc)
thanks
