[de_503]

i have an excel 2003 doc that i've been working on for the last several months that recently started acting up. when i open it, it looks like there's nothing in it, but the 3 pages of data is there, i can print it, i can send it to other people on other computers and they can open it normally, but i can't get it to open here.. i've tried reinstalling office, i've tried saving as a new file. i can't figure it out.. help?
