"Communication with server" error.

I'm using Orcad 16.6 Lite and I have used other versions.(16.2, 16.3, 16.5)

But I have some problems.

1. Starting up time is too long. It starts about 5 minutes later.

2. When I make a new simulation profile or run PSpice, "communication with server..." message is displayed at status bar about 10 minutes. Then, 10 mins later circuit is simulated.

These problem occur all versions(16.2, 16.3, 16.5, 16.6) in my computer.

But, when I disconnect the server, OrCad works well.

What is the problem?
