XP installation problem

Hello,

My computer runs Windows XP 2002 and has one DVD-ROM and one DVD-RW drive. A week ago I replaced my DVD-RW drive with a new one. Both drives were tested and worked fine but a day later the operating system could not detect the DVD-RW drive or the DVD-ROM despite the system setup detecting both drives (Corrupt driver ERROR 39). The hard disk was full so a system restore did not work. I tried repairing the installation but before it begins installing devices it cannot find the DVD-drive so the installation fails. Installing a new copy of Windows XP worked though, but the administrators account is not accessible. I wonder whether it is possible to migrate the applications to the new installation as well as access the administrators account.
