I use my laptop at the office and at home and it has different accounts profiles. Installed Logos with the domain user and recently had to remove that account to recreate it with a new one. I forgot that Logos is not installed in Program Files but the user appdata\local directory so I lost all files and have to download everything and do the indexing again yikes!. This time I installed it with the local computer administrator account. Just to remind you so you don't get the same trouble.
