Everytime i try to do a unused disk space task on the on demand option. Earser will begin erasing without a probelm for like 5 mins then windows error report comes up saying it has to close the program and its sorry for the inconvience. So i tryed reinstalling it and i have tryed running the task over and over again. But the thing keeps telling me im S.O.L. So is there any quick fix for my problem? Thanks.
