Also, it may be worth contacting the package authors. They seem to have published this package in 2013, and I think we were on Stata 13 or 14. I suspect some syntax got changed internally. It will run correctly if you set your Stata version to 13, i.e.

version 13
zinbcv init_count stable_dem1 stable_aut1 redem1 redem1_pautdur1 redem1_pdemdur1 growth prop_demsregion1 riots1, inflate(stable_dem1 stable_aut1 redem1 redem1_pautdur1 redem1_pdemdur1 growth prop_demsregion1 riots1) vuong nolog

Thanks for giving the solution to this issue, that is still there in the moment I'm writing. I followed your suggestion and wrote to the command's authors.
