I purchased a 180 day trial version with disc in Jan 2010, installed into computer and the motherboard died. I purchased new computer with Windows 7 (previous computer was Vista) and tried installing and it won't work. I uninstalled everything Office and tried downloading the 60 day trial, still won't work as I get the activation expiration date of Dec. 31, 2002. Any ideas as now when I try to download from the website, it tells me I have downloaded my alotted number of times - still have no working programs and need them for a class - must be microsoft 2007 pro. Any help is appreciated.
