Installed the trial version of CS5.5 but serial number problem

I have downloaded from the Adobe website the Windows version of Adobe CS5.5 Master Collection onto my computer and can get the programs to run only if I install as a trial version. I have a legitimate for serial number for Master Collection. The installer clearly displays the words Adobe CS5.5 Master Collection in the top  left corner of the installer.  There is a drop down menu to select product, but while I can see other CS5.5 products, none of these menu items is Master Collection. I  also tried using the serial number one product at a time, by installing InDesign, I can see the product up and running on my computer, but according to the installer:  "The serial number you entered is valid but a qualifying product cannot be found on this computer". 

I also did try opening the adobe site while logged in, I don't know if that is the same as Adobe Live. Are CS5.5 Master Collection products connected to the CS live?  I tried to register through that and got the message ''Could not start your CS Live subscription, try again later''.
