Help with Protections ASAP

[nutmeg]

Hello, I have created a large workbook with 274 worksheets. It worked fine
until last night I saved it, went to General Options and saved it with a
Password. On opening it today, it will not let me edit any of the cells or
perform any calculations. I only put the password on the open not the
modify.

I went back in and deleted the password but it still won't let me change any
of the data on the any of the sheets.

Can anyone help me with this, I am desparate.

Thank you,
IEJ

Thank you, I did that and the same problem exists. I tried the Detect and
Repair on the Help menu and it says it can't find a file name PROPLUS.MSI.
Any idea what that might be for.
