Since this thread was started i sent an e-mail to the DH PE team to report this bug and an update was promtly released to fix this issue, so this issue is now resolved.
A big thanks to the DH PE team.
I purchased DC PE a couple of weeks a go and have just used it today, it worked perfectly but i think i may have found a bug in the backup feature.
When i go to Tools > Backup/Log and delete all backups there are allways files and folders left undeleted, i have included some screen shots so you can see what is happening and what files and folders are left undeleted after cleaning all backups.
As you can see in the above screen shot thare are no File Backups left to delete and its the same in all catagories, File Backup, Registry Backup, Directory Backup, Full Registry Backup and Log Files.
In the below screen shots you can see all the files and folders left undeleted after deleting all backups.
Thanks in advance!
