first of all: Awesome plugin,
The first time I used it it worked like a charm.
Then I had to update all my users since some info was missing, I tried every method but this wouldn't work since everytime I got the This email address is already registered error. Even when I didn't include the emailadresses I got this error. Since I used random passwords generated in excel and the accounts weren't being used yet (it's a study association and we are going to use the accounts for job openings and downloads in the future), i thought i'd just delete them all and re-upload them with the correct information.
Now I still get this error, i checked the entire support page, tried re-installing the plugin, checked phpMyadmin and found no references to the users.
Can you help me with this?
