LUA Error Regarding Meth Addon

I seem to have run into a problem after installing an addon off ScriptFodder. Any help is appreciated! :c

[ERROR] A runtime error has occurred in "addons/darkrpmodification-master/lua/darkrp_modules/hr_cm/sh_hr_cm_darkrp.lua" on line 21.
The best help I can give you is this:

'HR_CrystalMeth' is being indexed like it is a table, but in reality it does not exist (is nil).

	- You either have 'something.somethingElse', 'something[somethingElse]' or 'something:somethingElse(more)'. The 'something' here does not exist.

The responsibility for the error above lies with (the authors of) one (or more) of these files:
	1. addons/darkrpmodification-master/lua/darkrp_modules/hr_cm/sh_hr_cm_darkrp.lua on line 21
	2. gamemodes/darkrp/gamemode/libraries/fn.lua on line 84
	3. gamemodes/darkrp/gamemode/libraries/fn.lua on line 84
	4. gamemodes/darkrp/gamemode/libraries/modificationloader.lua on line 86
	5. gamemodes/darkrp/gamemode/libraries/modificationloader.lua on line 147
	6. gamemodes/darkrp/gamemode/init.lua on line 86
------- End of Simplerr error -------

Contact the author of the paid addon. There’s nothing we can do to help with paid addons.

I see, well I suppose that’s what I should have done in the first place :smile: thanks a bunch!
