Did you actually read the error? Also, it looks like you downloaded the super old version... Download the Beta: https://www.thebuddyforum.com/wildbuddy-forum/228343-beta-wildbuddy-beta-pre-release-builds.html The bot is being reworked, since Wildstar was reworked. The bot needs to be updated for the patch that went live this morning. Try downloading the Beta client in about 4-5 hours.
You'll get a pop-up when you launch the beta version about rerolling down to an older version - don't do this, just click cancel/no and it'll work.
