Only certain sheets display data

I have a workbook that tracks overtime budget with a worksheet for each month. All the way up to July, 2007, the data displays in the sheets. Starting in August, the data doesn't display. This workbook is shared on a network and other users can open and see these sheets (with data) but i can't.

Any ideas? Since I'm the only one having problems i'm thinking it has to do with my excel settings.

I've tried:

Re-launching Excel
Manual Calculate (CTRL+ALT+SHIFT+F9)

Thanks

it could also be the way your company network is setup i had a similar problem with drawing data from other locations as the place i got my data from was lets say P:/spreadsheet_files and people who could view it was E:/MasterSpreadsheets/spreadsheet_files.

not sure if this will help just a thought though.
