Hello Theas,
Are you using Standard Accounts? Please try and see if a reinstallation of the program helps. You can find the latest version of Standard Accounts on www.standard-accounts.com. My suggestion is that you install the program in a new folder on your desktop and keep your old installation until we know for sure that the new one is working. Once you are in the program you can import your latest database backup so you can access your company again.
Best regards,
Edwin
