If you are on a company network, your system administrator is someone within
your organization. There is a setting on your computer that only an
authorized administrator can change. If it is your personal computer then
you should be the administrator and you can check to see if there is a
restriction on your files and remove it. Click ToolsProtection and if you
see Unprotect, click it. If it say Protect Sheet, then don't click it.

Then click ToolsOptionsSecurity and look at the settings for worksheet
protection there. However, if these settings were checked, you should have
gotten a notice when you opened the file.
