you need to edit the profile your trying to load. theres a minlevel and maxlevel, change the max level number to 91 and save it, then reload the profile and you should be good to go.
thx for your reply, but I haven't load any profile yet, I can use the BGbuddy very well. could u plz tell me which profile should I load?
You should load the profile for Gatherbuddy2 that you want to run. Based on your professions, level and what you are trying to gather. The bot does not come with an extensive list of included profiles, you have to download them yourself.
