What is the issue?

Please provide any additional information below.

today i decided to try Everyquest i've downloaded it from Wointerface that was version 2.1.9 but as soon as i've logged into WoW my problems started  i've opened up Everyquest and then choose zone and that worked fine but then i tried to pick up quest and get this information: Everyquest Gained quest:unable to get quest information from the DB

after that i've tried to mark and unmark the boxes Save zone and track zone but that didn't help either

after that i've tried to instead download the beta version from Curse and then i saw a box with red text Interface\Addons\EveryQuest\core.lua:1129:attempt to concatenate local 'uid'(a nil value)

i also tried to turn off all my other addon but the problems keep continuous

i also tried to purge old data that didn't work either

i also tried to not use the button in Questlog but that didn't help either

what should i do? i want to use this adond it would really help me

is there any why to use the addon and manually keep track of whitch quest i have done and not without seeing the words all the time Everyquest Gained quest:unable to get quest information from the DB in the chatframe

(i'm not so good in english)

hoope someone can help me with this
