I Googled
the program has expired error and found quite a few references, although they had to do with games like Diablo III, Skyrim, Battlefield and suchlike.
Those who had found a solution all pointed to the software mentioned in this reply on the Steam Users forum:
"I have recently built a new computer and had the same problem. It was caused by a program which came with the motherboard called Virtu MVP. If you uninstall it your problem should go away. A pity because Virtu MVP combines the processing power of your graphics card with the one integrated into the Intel chip - quite useful! "
