I've tried installing the bigger world map, the RTTSetup15, and the SoSv1.12 and every single file says the exact thing when i try to install it. <"Unable to find DIALOG.TLK">
It's really bumming me out and i have no idea how to fix it. I downloaded the patch from Bioware and the custom voice files from this site... That's all the mods i've installed. I don't know if that helps any but i hope i can get a fix for this soon... I've already finished the game over and over again but i still love it so much!! I was hoping i could download a few things to add to it a little bit.
Any help would be greatly appreciated!!! Thanks
