Admin blues

Hi All,
I run XP Home on a AthlonXp 2000+ with 1G memory. Some time back I lost the ablility to load programs from a CDRom, although if I copy the CD contents to the desktop and run setup from the desktop they install OK. Also, when I insert a CD or DVD, Explorer opens up instead of Media Player, even though I have changed the settings.
I changed the Administrator account to my name a while back; I am the only user and thought I had full admin rights. Do I need to create another account called "Adminstrator" in order to be able to control my computer?
Thanks, Chris

 

Boot into Safe Mode. The Admin login will be available on the Welcome Screen. Then, go to Control Panel, User Accounts and see if you have Admin rights in your account.
