cant connect to excel
I've had this problem before. Try doing a repair on excel first, that didnt work for me but it might for you. If that doesn't work, I remember I solved it by clearing all excel registry keys using regedit (look up online how to do it) and then restarting excel. If that doesnt work, clear your registry of excel key again and then reinstall excel.
remember to create a backup of your registry before you do this
