To make sure I am understanding this correctly, all of my GL files in my Data folder are named GL*.DAT. There are 93 in total. I am going to move these to a temporary folder and then copy all the GL*.DAT files from my back up to the Data folder. I have a back up that was made immediately before the GL posting that crashed so I will try that one first. Maybe the posting will go through now that there aren't any GL files accidentally left open. I will keep you all posted (no pun intended) and really appreciate the support. I've never restored from a back up however I am assuming that since it is only GL*.DAT files that I'm replacing that I won't lose any other data from the other modules.

Andrew.. I will do the uninstall and reinstall while I'm at it. I assume I can install Ledger, then jump right to installing the latest service pack? In other words, I don't have to install each service pack that came before the latest one?
