When i try to launch the program, it says signing in, and then the program just disappears.  The icon in my dock just leaves and the program never opens.  I had version 4 installed but I unistalled it before the installation of beta.

What do you mean that the icon "leaves"? Does it disappear? What OS are you running? If you just mean that you are getting a crash, please enable and post logs. See my signature line for help.

Here are the log files.  I am using OS X Mavericks.

Appear that the problem is located here

[quote]Error opening database at '/Users/jayward/Library/Application Support/Logos4/Data/tue1d6s4.7ix/LibraryCatalog/catalog.db

Try deleting the catalog.db file and restart Logos. The application will then create a new catalog.

Just in case, I will add that the Library folder is hidden by default. Best way to find it is to use the Go menu in the Finder. When you depress the Option key, the Library folder appears in the list and can be opened from there.

That worked.  Thanks for your help.

Very pleased that I was able to be of assistance.
