Cannot save file
 

I have a file that is pulling information from several large files via
vlookups and hlookups. I've already broken all of the links of the larger
files and I've tried using shift-F9 to calculate and then save without
recalculating. The file isn't huge (about 2MB) but it still won't save! Is
there something I can do? This file is critical for a forecast tool I'm
developing and if anything I'd like to add to it.
