I cannot activate my account
So I have Hitfilm 4 Express 2017 for about a year now, activated and all, works like a dream. Now I downloaded the updated version "Hitfilm 4 Express" I opend it and it told me it was in demo mode and needed a code. I logged into my account on the website and there was the code for the "hitfilm 4 express 2017" and the one for "Hitfilm 4 Express" so I copied the code of the hitfilm Express one and it hat an error saying "Your serial is only valid for Hitfilm 4 Express" (Which is exactly what it was!!!!!) so basically I can't activate Hitfilm 4 Express because my code is for Hitfilm 4 Express...... Please help me out?
