New HD - Applications won't open

[magmac]

I just had the hard drive replaced on my G4 (tower).
When I got it home, things won't open!!!
Am I expected re reload applications after replacing a HD?
The icons are still on the dock. When I click on them, they bounce, display the little black arrow, then settle down and the black arrow disappears.

Example:
My scanner (Epson Perfection 1650)
Illustrator
Photo Shop

Do I take it back to the shop?

Help!
Magmac is MAD

Was the operating system reinstalled/ did they reinstall your applications as well?  If not I'd take it back and ask ..."how's come?"  After all, you paid them to do the job, right?
