I can not connect to Sample database VIP Task Manager gives the following error:

The possible cause of this issue is that "Firebird" database management system is not installed or started. To check it, please do the following:

1. Go to "Start -> Settings -> Control Panel -> Administrative Tools  ->Services. See the attached screnshot.
2. Check if " Firebird Guardian" and "Firebird Server" are started, if they are not, double click on them to start them.

If you don't find "Firebird Guardian" and "Firebird Server" in services, I recommend you to uninstall and install our program again:
1. Close VIP Task Manager.
2. Download the latest version VIP Task Manager:

3. Install it on your computer. I recommend you to read our Installation Guide:

4. Launch VIP Task Manager.

If that doesn't work you can download and install Firebird separately from our application.
