Hi, recently i've been having trouble with this mod and getting it to work, but I finally got it to run thanks to some things i've been doing, so I thought it would be nice to share my tips for anyone who is having the same issues.

TIP 1: Create a preset with your current mods, after that, install the addon and restart Gmod. IF IT WORKS, it means that a mod is causing trouble, or you have to many mods that can overwhelm others, causing some to not work or leave their effects unseen. IF IT DOES NOT WORK, refer to TIP 2 or 3. But after that, reload your preset with CMB TRACERS ON (make sure to select the "Activate" button when the game asks you what to do with mods that are not present in said preset). With that, you SHOULD be able to experience CMB TRACERS REWORK with your modpack. But if not, refer to TIP 2 or 3.

TIP 2: Go to Program Files (x86) > Steam > steamapps > common > GarrysMod > garrysmod. Then, delete the "cache" folder, after that, close your file explorer and reinstall the addon, then, restart Gmod. It's probable that an uninstalled addon could've left parts of it scaterred in the game files, especifically on your cache, this means that the remnants left behind could've caused errors and bug out other addons due to it's incompatibility.

TIP 3: This might be exagerrated, but if the tips above do not work, try UNINSTALLING all of your addons, reinstall CMB tracers.
...But if not, then, go to Steam > steamapps > common > GarrysMod and select the FactoryReset-GMod.exe, which will factory reset your Gmod.
I know, I know, it's pretty out of pocket, but if CMB TRACERS wouldnt've worked with the tips above, then that means that your Gmod is saturated of addons and whatever other errors consumed your files. Making it imposibble for some addons to work. I know its boring having to sit and install, manage, and customize your mods, but its better that than having to deal with a broken game.
Anyways, that was it, I hope you fixed your problems with my tips! If you're having trouble, don't be scared of leaving a comment, since someone else must be having issues with that, too! But yeah, that's it. Bye!
