Error encountered: CD key already in use.
It functioned previously, but now it seems unresolved. Many individuals have encountered the issue without success.
Only one installation is allowed before the key deteriorates. Even if the copied version is lost, it remains unvalidated.
I’m here to clarify this for you. I’m the individual TehMiik mentioned, and I confirm everything. I purchased the key from Amazon and it functioned correctly at first. After cleaning up my PC, it started requesting my product key again—though it indicated the key had already been used.
