If you are already using the old versions of XFactor , you SHOULD delete your registry entries that matches to
xfactor and
maydje and then start running XFactor v4.1 , just incase to NOT face with annoying errors due to missmatching entries with the OLD versions of XFactor. Just go to your registry
Start > Run > regedit , and then FIND all entries match to xfactor and maydje and Delete them, and then start using New X-Factor
v4.1
it works with that
