I made an nlited xp disc a few weeks back on an old machine that is now gone. I then wanted to change some of the addons and (remove a few and add some new ones). When I load the last session it has most of the settings but nothing shows up in the hotfix area. No addons or anything.

Is this because the direct hotfix integration box was checked or am I possibly doing something wrong? I thought the last session option would show everything on the disc and allow it to all be modified.

If anyone knows what is going on please fill me in!

Hmmm, it's likely the add-ons have either been deleted or moved to a different folder and as the preset is loaded, it does not include the add-ons since it can no longer find them.

Or you nLited twice in which case the last session only shows the second modification.
Or you selected to not save the "last session" on the iso and a previous file remained, not overwrited but not erased either (I don't know if that would be the case though).
