Good afternoon, some time ago I bought the LFS S3 license, after a few days I formatted the PC and lost the license, on the website it says that I only have the demo license, but I bought the S3 license.
Formatting PC cannot affect your licence status,so the problem must be somewhere else. I've seen multiple times people complaining about lost licence status,which eventually turned out to be a mistake - they simply logged in their 2nd account,do you have multiple accounts? The account you posted from has no online activity at all.
Where did you buy the LFS S3 license? Is it a reputable address? I see that you registered an account in 2017 but have only created 1 new post so I think you don't have just 1 account??
