Problems with Rhino 5.0's floating license!

Rhino Rhino for Windows
1

I have a next problem - I installed some copies of Rhino on computers in my local network. Zoo yesterday showed all working copies in network, but now all my programs can’t start because Rhinoceros can’t look floating licenses. When I start program, it works about 1 minute and closes with message "There was a problem communication with “server”. Help me please, I need working programs very much =3 PS. Sorry, my English can be bad, because it’s not my native language

Does any of this information help?

Thanks, but I’ve read guide=( Problem is actual now. I don’t understand why Rhino can’t see licenses. Local network is working well.

I am sorry, but I don’t understand this. What is your native language?
