Hi CR DanceXtreme, 

Thanks for reaching out. KB 10403 on How to use Database Utilities (Sage_SA_dbutil.exe) is a match for the issue you've described where "When I try to open Payments Journal window it shows a blank page".  If you're on a newer version, you'll want to try the steps below for a database repair:

Sage 50 2008 or higher:

1. Backup your data from Sage 50
2. Close the program.
3. Browse to C:\Program Files (x86)\(Sage 50 Version 201x)\
4. Locate and double-click on the executable file:
   • 2008-2009: SimplyAccounting_dbutil.exe
   • 2010 + : Sage_SA_dbutil.exe
5. Click the Browse button in this Database Utility tool
6. Browse to the folder where your data file is located (the .sai file), select and open it
   • Ensure the file is locally on your computer, if it is on a server, copy the file on to the local machine to run the dbutil and then copy back to the server
7. Select all 4 check boxes and then click the OK button to begin repairing the database
   • The window will remain on displayed until the process is complete. A window will appear a message stating that Your tasks are complete
8. Press OK then close the window
9. Start Sage 50 to verify that the problem was fixed

Note : if you having issue running the utility please verify and make sure sysadmin does have third party rights

1. Log into Sage 50 as sysadmin
2. Click Setup, Set Up Users
3. If asked for a password, enter sysadmin password
4. Select the user you log into the third-party product with and click Modify
5. Select Read-only access or Read/write access to Third-Party Products and click OK
6. Try utility again
   
   

Hope that this helps you!
