Windows 8.1 OEM 정품인증 오류

최근 LG 그램 14 노트북에 문제가 발생해 다시 8.1 OS로 재설치했습니다. 그런데 지금 정품인증을 시도했는데 이 제품키가 다른 PC에서 사용중이라는 메시지와 동시에 0xC004C008 - 제품키가 잠금해제 제한을 초과했다고 나옵니다. 분명 제 PC에 설치한건데 왜 다른 PC에서 사용중이라고 나오는건가요?

참고로 명령 프롬프트에서  Licensingdiag.exe -report %userprofile%\desktop\report.txt -log %userprofile%\desktop\repfiles.cab 명령어를 실행한 후 report.txt 파일 내용을 참조해 로그를 작성했습니다.
