Power Geopak (SS10) crashing when selecting PGL chain in Design & Computation Manager to plot profiles

My Power Geopak (SELECTseries 10) crashes every time I try to plot a profile. When I use the Design & Computation Manager as soon as I try to choose my PGL Chain the program freezes, and then I have to force quit it. I get the same result when trying to use the Draw Profiles tool (which I prefer) and try to select the PGL Chain.

Has anybody else experieced this and solve it?
