So heres the deal: my addon (its a levelling addon) works on my buddies computer but when I try it on mine I only get errors. The addon is dereks levelling guide (what can I say.. lol) and the error Im recieving is

Interface\AddOns\DLG\Interface.lua:233: bad argument #1 to ���pairs��� (table expected, got nil)

Again Im not sure why it works on his computer but not mine. Thanks for any help. And if you need more info please let me know, thanks.

Please post this on the addon's project page and not here. Thanks :) Another addon I can suggest for leveling is Quest Helper, check it out.

Best of luck!
