Vista - require password when computer wakes problem PLEASE HELP

Hello, my daughter and I share the same computer. She changed my account that was administrator to Standard and then clicked on this : require password when computer wakes. Now everytime i download something the download works but then the security question pops up and says i require a password and i have to type it below but it wont let me type it below because the setting : require password when computer wakes needed administrator account to function but now because i have standard it wont let me type a password. i tried changing the account type but the same thing happens and i tried : change settings that are curently unavailable and its the same! please help me because it wont let me download stuff for my work . thank-you
