This issue is usually caused by two possible problems:

a) You have different Projetex builds installed on your Projetex Server and Projetex Workstation. In this case, download the latest Projetex build and install it on your server and workstation computers over the existing copies of the program, without uninstalling beforehand. You can always download the latest builds of owned products at your personal profile at http://clients.translation3000.com 

b) If you are sure that you have the same build on both computers, please make sure that:

- The Server is active and the database is in the Online state.

- Ports 212 and 47111 (or 211 and 47110 for versions of Projetex prior to Projetex 3D) must be open in the Server machine's firewall.

- Projetex.exe must be added to the trusted applications list on Server and Workstation PCs.

- fbserver.exe must be added to trusted applications list on Server PC (only for versions of Projetex prior to Projetex 3D).
