Unable to activate my SDL Trados Studio 2017 on new laptop

Hi! My laptop crashed recently and I had to replace it. I bought exactly the same laptop and I'm using my old hard drive as I wanted to keep my Windows 10 and all the software, incl. Trados. However, I am unable to activate my SDL Trados Studio 2017. It says Licence Expired even though there is no expiration date and the activation code doesn't seem to work when I enter it in the Product Activation window. Please help!
