Hi. I am having a problem on my other computer. On my computer i have XP Media Center 2005 installed. I just installed a new harddrive yesterday but today when i turned on the computer an error message came up saying that servicepack.exe is missing. I do not know what to do. Can you please help me fix this problem. I think it is a driver problem but i am not sure. I tried to find servicepack.exe on my drivers and utilities cd but i could not find it. I have my reinstallation cd but the problem is that i cannot reinstall anything because i cant find my cd key for it. Please help me. Thank you.
