I am trying to work on excel files on Windows 7 2010 Excel and when I try to open the files saved in XP 2003 Excel I get the message
The file youa re trying to open'www.xls'
, is in a different format then specified by the file extension...
when I try to pen it it looks like crap
I am opening it off of a thumbdrive (double checked to make sure that the files are in fact working...they openied great in 2003)
