My Endnote Library.enl contains an incorrect path

Hi everyone

My Endnote has just stopped working with an error message “My Endnote Library.enl contains an incorrect path”.

I have been using Endnote X7.3 Buils 8536 for about a week in a new HP Elite book running Windows 8.1 Pro. All of a sudden, yesterday the 4th April, it stops. Evrytime I start it such a message pops up and it is the end of it.

Any help will be much apreciated.
