重灌steam, 序號會不會不見? - Steam

沒把光碟帶在手邊.....
今天要玩的時候..一直出現錯誤訊息
-------------------------------------------
steam.exe(main exception):Unable to start steam Engine:
*steamstartEngine(0x13e868)failed with error 1:Protocolerror-not eoungh data
for extractnext
------------------------------------
請問這是什麼問題?
直接重灌steam需要重新輸入序號嗎??
