reverse-geocode error

[coyotespike]

After requiring [factual/factual-clojure-driver "1.5.2"], in my repl I then ran:
(require '[factual.api :as fact]), and then (fact/factual) with my information.

When I ran (fact/reverse-geocode 34.06021,-118.41828), I got the error message: IllegalStateException Attempting to call unbound fn: #'slingshot.support/throw-context clojure.lang.Var$Unbound.throwArity (Var.java:43).

In addition, (fact/multi {:query1 {:api fact/reverse-geocode* :args [34.06021 -118.41828]}}) produces the error:

{"query1" {"version" 3, "status" "error", "error_type" "Auth", "message" "Geocode has been superseded by geotag. Please refer to http://developer.factual.com/api-docs-v4/#Geotag"}}

Thanks for any help!
