If you only have this mod installed and you're still getting crashes, I suggest doing one or all of the following:

Verify the integrity of your game's files through Steam
Update your game
Launch directly from Origin

This is a pak that I've put together using Callyste's Lightsaber Color Editor. These are the saber colors that I've created, which make the lightsabers stand out a lot more than the default colors.

Version 1.2.0: After a LOT of trial and error, I've finally managed to tweak the saber colors in a way that I think a lot of people will be pleased with.

Version 1.3.0: In response to the May 4th update as it messed with the previous pak. I also added a new red color that will affect your new red crystal as well as other red wielding characters. The red is a bit deeper and richer in my opinion. 

Version 1.3.5: Updates orange and red

Version 2.0: Did some minor tweaking to most of the colors. 

Version 3.0: This is it. The last one. I don't plan on updating this any further because I believe the sabers are the absolute best they can get.

Version 3.5: I know, I know. I said the last update was it but this time it really is. Apart from indigo, magenta, and yellow, this tweaks all the other colors. I've made purple more movie accurate to Mace Windu's in ROTS, and I took out some of the yellow that was still in the orange.

Version 4.0: Another update. This updates blue, red, and purple.
