I called the customer service number on the LOGOS home page - it was answered immediately by a sales associate. When he discovered that I needed customer service, not sales, he transferred me - and put me on hold for 20+ minutes. I gave up.
My problem - it is my understanding that the update to LOGOS 5 is supposed to be an automatic update - but the update (after several hours of trying and waiting) would not start. I called for help, but could not wait any longer.
I have found a link for a manual update - I hope it works, without any loss of books or information. We shall see.
