Error

Hello, my name is Wellington. 

I have a problem with the CG 3900. The problem started when the computer battery ran low and we had to change it. From there the problem began when you click on the Galaxie Workstation icon and an error occurs:"Server connection: Unable to connect: EnxPooledTransportException during logon procedure at 142E830: NexusDB: : Cannot locate or connect to network server. [$2C0E/11278]".   Could someone help me please? Thanks. Note: All cables are connected.
