during the installation of SuperAntiSpyware 4.49.1000 uT crashed, not sure whether it is related (I am not going to try it again), and did not recover. every time thereafter starting uT it would crash, no crash handle/no dumps. uninstalled it, leaving the setting, and reinstalled but no avail, it just kept on crashing when started. only deleting resume.dat and resume.dat.old got uT back to work. however the torrents had to be rebuild and of course the ratio was gone with those files gone...
