Hello everybody,

I work on a PC with Mathematica 10.1 installed on it and with Windows 7 as the operational system. I want to connect to a remote HPC with Linux as the operational system, on which Mathematica 11.0 is installed. When I tried to run a Mathemattica 10.1 file in such a way (with the connection to HPC), i received the following output:

Mathematica 11.0.0 for Linux x86 (64-bit) Copyright 1988-2016 Wolfram Research, Inc.

Mathematica cannot find a valid password.

You will need a valid activation key and password in order to proceed. Go to http://user.wolfram.com to register your activation key and obtain the password.

Enter your Activation key [format xxxx-xxxx-xxxxxx]: Enter your password: The password you entered is not valid. Please press Enter to quit.

What have I to do for fixing this problem?

Sincerely yours,
