Pitbull and multiboxer v2 o.5 fighting like step children

I decied to add a couple of add-ons today but it seems that Multiboxer and Pitbull don't seem to get along together. Can anyone help me make them coexist? Here is the error message I keep getting: LibrockConfig-1.0: bar return from function "args" for 'pitbull". expected "table", got "string" ("@cache")

other add-ons I am using (But they don't seem to the ones causing the problem)
Automaton
Decursive
Pitbull
Quest helper
Lib:Ace2
Cartographer
group calender
lib:fubarplugin-2.0
twoboxtoolkit
dbm
multiboxer/pitbull experience bar
multiboxer v2 0.5

any help would be much appreciated!

I'm running those two without any issues. The only plugins you are running that I am not are:

Group calender
lib:fubarplugin-2.0
twoboxtoolkit

SOLUTION
1. Delete the MultiBoxer\libs\LibRockConfig-1.0 folder in Multiboxer
2. Copy the Pitbull\libs\LibRockConfig-1.0 folder in Pitbull
3. Paste it into MultiBoxer\libs\

thanks

If you use external libraries then this will never happen again. Here is the post where it is explained how to fix this.
