Missing part SW PDM

Hi all

i got a problem with a part that i can not open from my pc.

if i open a  ass with that part SW says " SW encountered a serious problem in the file"

if that file is open then it works fine and by my colleagues is all ok they don't get that message,has someone that experience? i already restart my pc and delete local cache and "check out" that part and ass and sawed it and "check in" but it did not work.
