Why doesn't my emachine w3611 preinstalled windows vista product key work any longer? It says its to long. I thought I typed it in wrong so I used the Auto detect and its showing the same product key that I put in. I went to the emachine website for answers but because my PC is older and the product key isn't recognized . They wont give me support and said to ask here. I also don't have my disks any longer and I don't even know which ones I need in order to do a clean install. Do I have to pay for another product key because my computer is older and no longer in warranty?? I am even willing to buy a recovery disk or pay for a download but I don't even know where to go to do this. Please any help would be appreciated. ( I am trying to change the hard drive in it and want to be prepared with all that I need to do this) Thnx!
