Diablo 2 installation problem XP

So i recently dug out my old Diablo 2/LoD CD's in order to register my CD Keys to my Battle.net account...

I tried installing from the CD and whether I put the expansion or original discs in, it would tell me to "Insert Expansion Disc" every time.

So, frustrated, I downloaded the digital copy from Battle.net... When I launch this installer it pops up with "Play Diablo 2" instead of Install Diablo 2 like it should... When I click Play or Uninstall, nothing happens... When I go to Add/Remove programs, Diablo isn't on the list...

Any suggestions?

Think I figured it out... NEVERMIND!

Dude, can you remember how you fixed it? I am having the same problem and can't figure it out!cylon87
