About the first issue, read the readme, start a QB after you install BPCore Gold, then try to install anything else.
As for your second issue, it's quite possible that it's because it's missing an animation (or something like that), but I'm currently not sure.
It's also possible because the other function they overrided that this is happening.
[EDIT] Which version are you using? The one found on BCFiles? Or with my "patch" so to speak?
