    C4 not working with Windows 7 Professional


      I've had a new computer with windows 7 professional and have put CS4 creative suit on the laptop.  However, I get the error message "the serial number you entered is not valid"?  Can anyone help to resolve this as have contacted ADOBE direct but they were useless.  They said the serial number is valid but wasn't able to advise of resolution!!
