Reindexing after moving User Profiles to a D:\ partition

["Tom Nielsen" <tom@xxxxxxxxxxxxx>]

Recently my Vista OS was corrupted so I used the 'opportunity' to  
installed a larger drive. I wanted to separate my user data from my system  
data, so I created a Users folder on the D:\ partition and then moved all  
the user profiles to D:\Users. However, I failed to change the paths in  
opera6.ini and several days later, when I realized new mail was being  
stored on C:\, I copied the contents of the mail folder on C:\ to D:\. I  
then edited opera6.ini, replacing C:\Users with D:\Users, deleted the  
lexicon folder and then ran Opera to reindex the mail, but a new lexicon  
folder was not created. Now when I click on a filter (folder), Opera  
displays the number of messages but none of the messages. I checked the  
stored folder and subfolders and the messages are all there, including  
those for dates before I moved to the mail to D:\ and those received and  
stored on C:\. Since the deleted lexicon folder was not created, I  
undeleted it, but htat made no difference.

How can I correct the indexing problem and have Opera display the messages?
