error 000599 in ArcGIS 10.1

Question

Hi,

I'm trying to generate Multiple Ring Buffers vis python tool from toolbox in ArcGIS 10.1. But when I change units into linear e.g. km or m, it crushes with this error, also dissolving is set on NONE and tackled outside polygon option. It works on different gdb properly. I've changed the XY extent in environment on 180/-180, 90/-90 and this also doesn't work. Coordinate system WGS-84. What can I do more? Or what I do wrong?

The error code 000599 refers to a bug NIM089961 and was resolved at ArcGIS Desktop 10.2.  Do you have the ability to upgrade to a new version of Desktop?
