I got Nubґs part but canґt get back on the elevator. I tried pulling the block off the elevator but Indy says he canґt.
Please help!

I had exactly the same problem, and I downloaded a savegame from some Indy-site. That worked, the only disappointment was that I lost about 75% of my money, so I was afraid I would never make enough again for the secret map. But I did and at the end I did not have to spend it after all because I was automatically transferred to the extra level at the end of the game. I you want this savegame, let me know I and I send it to you. Bye!
