how to remove workbook password.

Hi, I accidentally placed a password in my workbook. Now, every time I open the xlsm file, it requires me to input a password. (thankfully i was able to guess the password.) I tried protecting and unprotecting the workbook using the one under review tab, but it's still there. This happened after tinkering the macros. Any ideas?

Given use of XL2007 see: http://office.microsoft.com/en-us/he...48333.aspx#BM4

note: obviously (per forum rules) we won't help if you don't know the password but you state you do.
