My Glasswire has suddenly reverted to free version. I don’t know where that activiaction code is.
I bought it thru steam, but steam does not show me the activation either
What does Steam show exactly? Nothing? Have you asked them or opened a ticket with them? It’s very strange your Steam code would just disappear after you paid for it.
We cannot lookup Steam orders, otherwise I’d do that for you right away.
Please open a ticket with Steam and if you get no results please let me know and I’ll escalate the issue with them. You can email me here and please link to this thread: https://www.glasswire.com/contact/
