I have a password protected access database which was using for about 2 years. Yesterday I tried to open the same with correct password but it says "not a valid password". This is a *.accdb file. I tried to open the same in a different computer with same password and it works perfectly. There is no typing mistake here since please. Have anyone seen this kind of issue before or do you have any idea what is happening?
My OS is windows 8.1 with office 2007.
