Yuka Laka Droid shop problem

When I installed a certain mod, called "EnterJabbasPalace project", it made me unable to enter Yuka Lakas droid shop on Tatooine where HK-47 is, because of this, I've have uninstalled the mod and reinstalled KOTOR 1 but the problem still persists and I think it has something to do with a modules file being missing but yet again I reinstalled KOTOR 1 so there shouldn't be a problem. Any ideas?

Thanks.
