I was adding some new mod force powers, full force and high level. For some reason, they would make each others descriptions blank when used at once. So, I went into TalkEd and manually added in all of the names and desc (it was at the very end, like they were all done with new entries) and when I loaded KOTOR 2 up the launcher was messed up.
EDIT/UPDATE:
This has now developed into a much larger problem, no doubt routed in stupidity and amateur mistakes, but a development none the less. Now my dialogue.tlk seems entirely wiped, any every time I reinstall it auto empties itself.
I can't fathom a way to fix this, unless I can find some where to download the original dialogue.tlk otehr then my disc. It seems odd that this issue would continue to remaina after a total reinstall.
