I am using 1.7 and when I tried to upgrade it, I get a message that
Module Install: Another module is already using directory: "/home/joey2509/public_html/modules/mod_uddeim"
Have you deinstalled the old module first?
If so maybe something went wrong and Joomla was not able to remove the directory. In that case do this manually.
