I installed Dropbox Full Backup Pro and ran the backup, but ended up with two instances running. I deactivated and deleted the plugin and tried to reinstall it, but it’s telling me that the directory already exists and the installation fails.
Installation process and removing process for each plugin is executed through WordPress core system.
