I removed Word and tried to reinstall but they want a serial number. I put in the numbers and letters I found on the disc but it said they were invalid and to contact Corel. We bought the Computer about a year ago and I can't find the paperwork that came with it. If I would have known that I would have to put in serial numbers, I probably would have tried to fix the problems as opposed to removing it and trying to reinstalling it. Does anyone know where I can find the serial number? I went to Corel's website and they have an 800 number and I copied it down and I will call tomorrow if no one knows where to find this number that they want. I would appreciate any help.
