Hysys license

Hello all ,

I'm using HYSYS for years ,the last week I have changed by eror the time and date of my computer , then I corrected it , but I have gotten a license error on hysys .

Now hysys works perfectly but the date is set to february 2017 , when I change to the current date , hysys stops working .

I really want that my computer works on the current date because it gives me error on internet surfing .

I'm wondering if anyone could guide me on this problem ?

Thanks a lot !

Regards !

Did you try to re-install Hysys? If you did and still not working, try cleaning the register.
