Security to access Fluid Payment Request

We would like to utilize the Payment Request functionality using Fluid.

However, when I try to add a new Payment Request the following error generates: 

SecurityException: You do not have access to Activity Guide Instance 'AP_PR_H_AG'. (263,90).

I ran a trace and the trace (in part) shows the following:

Stmt=SELECT VERSION FROM PSVERSION WHERE OBJECTTYPENAME = 'SYS'

Stmt=SELECT OPRID FROM PSOPRDEFN WHERE VERSION > :1

           return stack:

           return value:

           Str[10]=AP_PR_H_AG

           Temp=#0  Value[10]=AP_PR_H_AG

Stmt=SELECT ACTIVE_FLAG ,PACKAGEID ,QUALIFYPATH ,APPCLASSID FROM PS_PTAI_GP_DSTYPE WHERE PTAI_GPDS_ID=( SELECT PTAI_GPDS_ID FROM PS_PTAI_LIST WHERE PTAI_LIST_ID=:1)
