Errors are fun!

I've been getting errors a lot since 6.2 hit, and i think it has to do with realui_config, but i don't really know how to solve it so i thought i'd ask here.
Looked through some other threads and i don't see peaople posting about this one.
Getting it when i try to open the realui config via either /realuiadv or the escape menu, and when i'm opening the config for realui related addons (bartenders /bt for example produces the same error).

Here they are:

5x nibRealUI_Config\Config.lua:1535: attempt to index local 'spellData' (a nil value)
nibRealUI_Config\Config.lua:1535: in function <nibRealUI_Config\Config.lua:1532>
nibRealUI_Config\Config.lua:1565: in function 'createTraker'
nibRealUI_Config\Config.lua:2029: in main chunk
[C]:: in function 'LoadAddOn'
nibRealUI\Core.lua:596: in function 'LoadConfig'
nibRealUI\Core.lua:469: in function <nibRealUI\Core.lua:469>

9x nibRealUI_Config\Config.lua:123: AceConfigRegistry-3.0-15: RegisterOptionsTable(appName, options): 'options' - expected table or function reference
[C]:: ?
...-3.0\AceConfigRegistry-3.0\AceConfigRegistry-3.0-15.lua:318: in function 'RegisterOptionsTable'
nibRealUI_Config\Config.lua:123: in function <nibRealUI_Config\Config.lua:117>
nibRealUI_Config\Config.lua:343: in function <nibRealUI_Config\Config.lua:337>
(tail call): ?
nibRealUI\Core.lua:469: in function <nibRealUI\Core.lua:469>

I have tried redownloading the ui multiple times, as suggested in another thread, but it doesnt help, so i'm kinda out of ideas here.
Any help is appreciated

Interesting, when logging any of my other alts i dont get any of those error messages (damn have i really only played my monk main since 6.2 hit :O).
Suppose the error is the initilazation of my monk (main) or something?
