On the Server

First check that the firebird server is running. Go to the Task manager and select the services tab. FirebirdServer should be running. 

If it is not running, then click Open Services, find the FirebirdServer and right click and select Start.

If it is not in the list, then go to Add/Remove programs and uninstall both the Firebird Server and the Client. Then go to C:\Program Filess (x86)\Veculim and run FirebirdServerInstall.exe and use the default prompts. Then run FirebirdDriverInstall.exe and use the default prompts. Check that the FirebirdServer is running as per above.

Run Veculim and make sure it connects. If it does not connect, but the firebird server is running, then disable the antivirus and re-check.

Reboot the PC and make sure that Veculim connects after a reboot.
