Have Office 2007 disc from collage where I teach (legal with license and all). All fine of 32 bit HP. Loaded on brand new Acer running Windows 7 64 bit. Loaded Office Pro 2007, loaded and accepted key, all info transfered, but when try to open any app (Outlook, Word, etc.) pop-up says I must register, do I want to use on line or phone. When I choose online, another pop-up says can't comminicate, try in a few minutes. (internet works just fine). If try to select use phone, window goes away, no phone number, and most features are locked out. Collage IT says nothing wrong with license, it's drivers. Where can I get drivers or is it something else? HELP!
