Problem with octave

Hello there this is Rahh and was an octave user and  used this software
for  some time ,  at first it was working  fine ,   but now it won't even
open i think it is because I ran some intresting commands ( or may be heavy
for this software ) and  the problem started from there ,  I click on the
icon and shows me some blank window but doesn't display the octave desktop
and sometimes it even opens but just  for like a sec or less than that and
then it closes automatically , there is no problem with GNU octave ( CLI)
but the graphics window opens through  GNU octave (GUI) and as it is not
working so I am not able to use this software properly  please help to
sought out this issue asap
