I recently ordered the NLT Study Bible which I received on CD as no electronic version was available for Logos4. Tried to install it off the CD but couldn't find it in my Library afterwards, so next I tried unlocking the resource using the Libronix Digital Library System. However, when I enter the unlock code that is printed on the back of the CD sleeve, all I get is an error message saying that the code is incorrect. Am I doing something wrong? Thanks.
