Paper2 Library Sharing problem.

When you share Paper2's database folders, you may get following error message.

This is happened by accessing database file at the same time from several computers. I fixed this problem using "sqllite" to create a new database file.

Follow instructions shows how to create new paper database from the corrupted database file.

1. Download SQLLITE binary file. 

(http://www.sqlite.org/download.html)

2. Run terminal

3. Run following command in the terminal
     teminal > sqlite3 Database.papersdb

    //next command is check your database, if your database has a problem, errors occur.

    sqllite3 > pragma integrity_check;

     // If you get no error message, Paper2 running problem is not the database problem.

     //Next command is create new database.

    terminal >  echo .dump | sqlite3 Database.papersdb >  DatabaseNew.papersdb.sql 

    terminal >  sqlite3.exe -init DatabaseNew.papersdb.sql  DatabaseNew.papersdb

    //change DatabaseNew.papersdb to Database.papersdb, Before changing, backup your original Database.papersdb. Because there are possibly to loss some records.

    terminal > cp  Database.papersdb DatabaseBackup.papersdb

    terminal > cp  DatabaseNew.papersdb Database.papersdb
