I having trouble with Excel 2002 on my folks machine (a 600Mhz Celeron with 256Mb RAM running Windows XP SP1a). What's happening is that normally, when you double-click an excel file in Explorer, Excel will start and load the file but now, for some reason it doesn't. Excel loads, but the file won't. You can open the file manually from with Excel afterward so it hasn't hung up, it just won't load the file. I've repaired office, reinstalled it and even uninstalled and reinstalled it manually but still nothing. Short of a complete reformat, is there anything I can do to fix this?
