Is there any way to recover WMP9 after nLite removal?

[har-vas]

Hi. I made an error and I understood it later. I have removed the WMP9 with nLite and now I can't install in any way the WMP10! I also tried to slipstream the latter with two relative tools, but neither worked. I read then that for the slipstreaming process to work, the WMP9 is needed. Here is my question: How can I now step in surgically to recover WMP9 in my I386 folder? Which files (and file entries) should I copy from a Windows XP SP2 CD? I have already copied one file which was needed for the "WMP10 Slipstreamer v3" to work (WMP.IN_ or something), but despite the successful message of the program and the presence of WMP10.cab in my I386 folder, the player is not actually installed. As you understand, I don't want to start the whole process from the beginning, just want to erase that mistake and then slipstream the WMP10. Please help.
