[PD] curve object not working right

[nosehair911 at bellsouth.net]

hello,
When I use the curve object it wont render past 10 inputs.  For example [curve 10] works but [curve 11] 
or above doesnt.  Is this normal and if it is not what do /i do to fix it.  It is the latest gem running on either 
PD .39.2 or .40.2 os 10.4.9.

Thanks,
Alain
