the Curse of Monkey Island disc 2 problem

[Jitsu]

So I finished playing the first disc of the Curse of Monkey Island and then it said put in disc 2... I did and now it says this message:
" Console is ready.
Debugger started, type 'exit' to return to game.
Type 'help' to see a little list of commands and variables.
ERROR: (87:29:0xD44): BundleMgr::open()Can't open bundle file: musdisk1.bun! "

When I type in 'exit', the window just goes black. If I click around or anything, it says 'not responding' at the top next to the title.

Help? I was so happy to be playing MI again... now I can't continue.
