Microstation v08.11.05.17 / Checking-out license issue

Hello,

When launching Microstation a pop-up window shows up referring that ‘The session has not been activated and will timeout in 15 minutes.'

We tried re-checking out the license, sometimes it says that a problem occurs when contacting server and sometimes confirms that Select Activation Key is activated. Although the issue still remains.

Any assistance would be appreciated.
