cxcalc command line license

Hello,





I'm having a problem running cxcalc command line but has no problem running the GUI. It looks like a license issue, but I don't understand because the license was installed and the GUI works. I'm running it on Linux. The error message is following. Could anyone provide a solution? Thanks in advance. -- Qing
